Answer:
A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains
Explanation:
Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.
Nucleic acids tend to form linear chains from the monomers called nucleotides. Nucleotides have three components: nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.
Hence, the correct option is "A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains".
