Today's cells contain RNA molecules that perform catalytic activity.

Translation and splicing are two biological processes that depend heavily on catalytic RNAs.

Many of these ribozymes' catalytic mechanisms are just beginning to be understood, and they demonstrate that catalysis is always carried out by RNA, whether it is acting alone or in conjunction with proteins.

Catalytically active RNA molecules are ribozymes. Ribozymes come in a variety of sizes and forms in nature. DNA has various benefits over proteins and RNA as a synthetic catalyst that has been identified through in vitro selection. Deoxyribozymes' expanding range of reactions is expanding our fundamental knowledge of biocatalysis and enabling applications in both chemistry and biology.

Answer: Competition for territory and other resources acts to slow the growth rate of the population

Explanation: Mountain lions are solitary animals who live on mountains of colder areas and hunts on prey like deer, rabbits, sheep, and goats. Every mountain lion has its territory and aggressively defend their territory from other members of their population.

So when the population of mountain lions will increase the competition for territory and other resources will also increase and in ecology, we have learned that competition is a negative interaction between two individuals which decreases the chances of survival for at least one individual.

So due to competition growth rate of the population will slow down to decrease the competition. Therefore, the correct answer is B. Competition for territory and other resources acts to slow the growth rate of the population.

The gene therapy can be attempted to treat achondroplasia is by RNAi that knocks down the mutant FGFR expression, Adeno-associated viral (AAV) vector that carries the wild-type FGFR and CRISPR with the wild-type FGFR donor DNA.

Gene therapy is a cutting-edge method for treating or preventing genetic illnesses. Correction of the specific DNA sequence would repair the protein, curing the disease since mutant DNA in genetic diseases codes for mutant proteins.

Gene therapy can make advantage of RNA interference. By blocking the production of the proteins that the genes code for, it is a method for "silencing" genes. It is a form of gene therapy that utilizes the transition between DNA and protein.

AAV-mediated gene targeting refers to the homologous recombination process through which AAV vectors can integrate. Thus, this vector that carries the wild-type FGFR can be incorporated into the achondroplasia patient.

Using the gene-editing tool CRISPR/Cas9, it is possible to add, remove, or modify a specific section of a gene's DNA sequence. Thus, the damaged section of the mutant FGFR's DNA can be removed using this technique.

Answer: There would be no life. Life would not be.

Explanation: Without ribosomes, there would be no proteins. Ribosomes contain RNA and proteins that cells need for survival. Cells can't survive without proteins. These tiny cell parts are therefore found in all living cells on earth. From large to small. Life would not exist without ribosomes because the cell's ribosomes contain proteins.

A genetic modification caused by the substitution of a single nucleotide for another nucleotide is called point mutation. Transition mutations and transversion mutations are two types of point mutations.

Point mutations are gene mutations that occur when a single nucleotide base in an organism's genome is changed, inserted, or deleted. Point mutations have a variety of effects on downstream protein product, with moderately predictable consequences based on mutation-specific features. In terms of protein production, composition and function, these consequences can range from no effect (e.g., synonymous mutations) to negative effects (e.g., frameshift mutations).

Conversion occurs when one purine moiety is replaced by another purine or one pyrimidine is replaced by another pyrimidine. The conversion occurs when the purine is replaced by pyrimidine or vice versa. The wrong mutation leads to the creation of a different amino acid. Missile mutations, also known as nonsynonymous alterations, alter one codon to produce another protein. The term point mutation is sometimes used to describe the addition or deletion of a base pair.

Each body part or system to the layer of the embryo from which it forms are (mesoderm, voluntary muscles, skeletal system); (ectoderm, cells of the nervous system, outer skin); (endoderm, gut, digestive organs).

The middle layer of the three germ layers, the mesoderm, forms during gastrulation in the very first stages of most animals' embryonic development. The ectoderm is the outer layer while the endoderm is the inner layer. Mesenchyme, mesothelium, non-epithelial blood cells, and coelomocytes are all produced by the mesoderm. Coels are lined by mesothelium. In a process known as myogenesis, mesoderm divides into septa (cross-wise partitions) and mesenteries (length-wise partitions), Mesenchyme primarily performs the function of myogenesis. Through intercellular signaling, the mesoderm separates from the rest of the embryo, and an organizing center then polarizes the mesoderm. The areas where GSK-3 shields beta-catenin from deterioration in turn dictate the location of the organizing center. The co-factor beta-catenin changes the activity of the transcription factor tcf-3 from repressing to activating, triggering the production of gene products essential for gastrulation and mesoderm development.

 Answer: Dinosaurs and Birds are most closely related to primates. This is the reason why phylogenetic trees are also known as evolutionary trees.

 Explanation: A branching diagram or tree illustrating the evolutionary relationships among distinct biological species or other entities based on similarities and differences in their physical or genetic traits is known as a phylogenetic tree (sometimes referred to as an evolutionary tree or phylogeny). One evolutionary tree represents all life on Earth and shows their shared ancestry. The century-old debate about the origin of birds has been resolved by the abundance of fossilized early birds and their closest relatives. The evolution of birds from the maniraptoran theropod dinosaur group has now been conclusively proven. Birds' bones resemble those of several maniraptoran species. Numerous fossils have demonstrated that maniraptorans laid eggs that resembled those of birds and that they also resembled birds in terms of egg-laying behavior.

Height, skin colour, and eye colour are three examples of polygenic traits in humans. Multiple genes control these characteristics.

A polygenic trait is one that is influenced by multiple non-allelic genes. These genes are known as polygenes. They are a group of genes that, when activated, express as a whole. Each one has an effect that adds up to the trait. Nonetheless, the effect of a single gene is difficult to distinguish, especially when a polygenic character is involved.

Polygenic traits do not follow Mendel's pattern of inheritance because multiple genes are involved. They are frequently represented as a range of continuous variation rather than being measured discretely. Height, skin color, eye color, and hair color are examples of polygenic traits.

Replantation and genetic engineering are two techniques that scientists utilize to enhance coral reefs or to manage the causes that cause coral reef degradation.

Numerous local and global problems, such as overfishing, pollution, climate change, and unsustainable coastal development, are continuously putting stress on coral reefs. Scientists have come up with many ideas to improve the survival of coral reefs. The two main methods are replantation and genetic engineering.

Both land-based and marine nurseries are capable of growing coral. Pruning and propagation are two of the most frequent techniques used to cultivate coral. We cut off a tiny piece of wild coral, bring it back to the nursery, and let it continue to grow there. We return to the reef to transplant it once it has grown to the proper size. In a controlled environment, we can produce more biomass this way.

The objective is to develop new coral breeds that are better able to withstand intense heat. Scientists are developing several coral species in the lab by genetic engineering to make them more heat tolerant. Coral can also be grown in hotter water to achieve this goal. Another strategy is to concentrate on the algae, which coral rely on for nutrients and oxygen. Scientists want to help corals fend off bleaching occurrences by developing new varieties of heat-tolerant bacteria and algae.

Some of the ways one can follow to save the destruction of coral reefs are safe boating, usage of non-toxic sunscreen, usage of green fertilizers, water conservation, and volunteering.

Refrain from touching or anchoring the boat on reefs. The delicate coral organisms will be harmed by contact with the reef, and anchoring on the reef can cause coral death.

Coral reefs have been demonstrated to be poisonous to a number of common sunscreen chemicals, including oxybenzone and octinoxate. So use sunscreen that is non-toxic to corals.

Because nutrients (nitrogen and phosphorus) from excess fertilizer use on lawns flow into streams and eventually end up in seas, this practice degrades water quality. These nutrient pollutants can damage coral reefs and pollute the water. Use environmentally friendly insecticides and fertilizers that won't affect coral reefs or other marine life.

Join a local beach or reef cleanup as a volunteer. Keep unwanted fishing nets and lines out of the water and off the beach. Any form of garbage can affect the reef and fish by polluting the water.

Only use water you actually need. The less water you use, particularly outside, the less wastewater and runoff will contaminate our oceans.

Only the dominant trait (tall) appeared in the F1 generation when Mendel crossed two varieties of a character (such as short and tall in pea plants). The F1 plants had a Tt genetic makeup.

Since all of the plants in the F1 generation have the genotype Tt and have the allele for tall height, they are all tall plants (dominant allele).

When a dominant allele is present, all of the plants have tall heights because the recessive gene is not expressed. However, the following genotypes are produced in the subsequent generation when the plants of this generation are self-crossed: TT:Tt: tt in the ratio 1:2:1. As a result, 25% of the plants contain the recessive alleles for both alleles. When the recessive gene is expressed, the plant is short and has a lack of the dominant allele. In the F1 generation, the recessive allele was suppressed; however, in the F2 generation, it was expressed.
