Question

DNA, RNA, and starch: What do these three important biomolecules have in common? A) They all contain at least one carboxyl group. B) The presence of at least one carbon-based sugar. C) The presence of strong hydrogen bonds between monomers. D) They all contain at least one amino group composed of a nitrogen atom. Submit

Answer 1

Answer: The correct answer is -

B) The presence of at least one carbon-based sugar.

Explanation:

RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are the two types of nucleic acids that are composed of nucleotide (monomer of nucleic acid).

A nucleotide has three parts, which are pentose sugar (5 carbon sugar), nitrogenous base, and phosphate group.

Starch is a complex carbohydrate as it is composed of several units of simple sugar such as glucose.

Thus, the presence of at least one carbon-based sugar is common in DNA, RNA, and Starch.

Answer 2

DNA, RNA, and starch have one thing in common that the three of them have atleast one carbon base sugar.

Further Explanation:

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of nucleic acid. They are the principal information carrier of the human or any living organism cell. DNA is a genetic material that is present inside the nucleus. RNA is also present in the nucleus but inside the region called the nucleolus. RNA participates in the number of cellular activities. They are composed of nucleotides such as purine and pyrimidine. The primary component of purine and pyrimidine has three major components pentose sugar, nitrogenous base and phosphate. The pentose sugar has a five-carbon chain.

Starch is a plant made food. The plants store the food in the form of starch. They are white granular organic chemical which is tasteless. It is insoluble in water and other solvent. The starch has six carbon, ten hydrogen and five oxygen molecules.
