In a protein, amino acids are interconnected through peptide bonds, which results in the formation of a lengthy chain. The bonding occurs via a biochemical reaction that eliminates a water molecule as it connects the amino group of one amino acid to the carboxyl group of another nearby amino acid.<span />
Answer:
b. the composition of R groups varies among the 20 amino acids in proteins, which can be either polar or charged.
Explanation:
As proteins consist of numerous amino acids connected together, their connections occur uniformly across all amino acids because one segment remains identical among them all.
The remainder of each amino acid, known as the R group, differs across the various types, defining their unique characteristics and contributing to their chemical properties.
Answer:
DNA
Explanation:
DNA serves as the cell's genetic material, often referred to as the molecule of life. DNA is deemed the molecule of life since it contains the instructions necessary for the cell to produce various proteins that facilitate the organism's survival by performing distinct functions.
Regarding the question, it is DNA that encodes the instructions for myofilaments, which consist of actin and myosin. Through transcription, DNA forms the mRNA molecule, which then undergoes translation to produce amino acids and ultimately proteins.
Thus, DNA is the accurate response.
