Answer:
Option smallest of the four main biological macro-molecules and building blocks of carbohydrates are the correct answer.
Explanation:
Nucleic acids are the bio-molecules formed by the polymerization of nucleotides .Two main nucleic acids are deoxyribonucleic acid (DNA) and (ribonucleic acid) RNA.
These nucleic acids are the building blocks of living organisms as they carry out many cellular processes like storage and carrying genetic information, directs cell activity and regulation- expression of genes.
DNA is the longest and largest macromolecule found in living things and they help with biosynthesis of proteins, where a single strand of DNA codes for thousands of different proteins but not carbohydrates as they are polymers of monosaccharides (C,H,O).
Thus, smallest of the four main biological macro-molecules and building blocks of carbohydrates are the correct answer.
ll Carbohydrates contain these three elements (usually in a 1:2:1 ratio) carbon, hydrogen, and oxygen. Monosaccharides - the simplest form of carbohydrates, contains one sugar. These are the basic energy sources for living cells. Examples of monosaccharides are glucose and fructose
Monosaccharide
Carbohydrates are essential macromolecules that are classified into three subtypes
the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules
