Proteins are the main structural and functional components of cells.
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid. The mRNA sequence is thus used as a template to assemble in order the chain of amino acids that form a protein.
The sequence of a protein is determined by the DNA of the gene that encodes the protein change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as α-helices and β-strands.

Peer review involves subjecting the author's scholarly work and research to the scrutiny of other experts in the same field to check its validity and evaluate its suitability for publication. A peer review helps the publisher decide whether a work should be accepted.
Answer:
Option. C.
Explanation:
Asexual reproduction can be defined as a type of reproduction, in which offspring are developed from a single parent and fusion of gametes does not take place.
As it involves only one parent that contributes to the all of the genetic material of offspring, the offspring are genetically or physically similar to their parents.
Thus, the correct answer is option) C.
251 million years ago, the Permian extinction occurred. It is the widest and most massive extinction that wiped out 85-90% of marine species and 70% of land vertebrates at that time. There were recorded low oxygen levels in deep and shallow oceans, extreme shift in the carbon cycle, massive eruption of a basal salt volcano in Siberia and the consecutive global warming that occurred evidently ended early prehistoric life.
Answer:
muscle contraction increases interstitial fluid pressure and compresses the blood vessels within the active muscle. As a consequence, blood flow is highest when muscles relax between successive muscle contractions.
Explanation:
