Question

Below is a model of a molecule.

Based on your knowledge concerning the molecule shown, which of the following statements is a valid conclusion concerning the purpose and function of this molecule?




a.The double nature of this molecule is directly related to the double nature of the cell membrane.

b.Without this molecule, genetic information would not be stored or transmitted.

c.This molecule has a phosphate and ribose sugar backbone.

d.This molecule functions as a catalyst for biological reactions.

Answer 1

b.Without this molecule, genetic information would not be stored or transmitted.

What is DNA?

DNA, a double-helix molecule, is essential for storing and transmitting genetic information. It encodes instructions for protein synthesis and ensures accurate replication, enabling the inheritance of traits. Without DNA, the fundamental basis for the continuity and diversity of life would be compromised.

DNA has a double-helix structure composed of two strands containing nucleotides with deoxyribose sugar, phosphate groups, and nitrogenous bases (adenine, thymine, cytosine, guanine). Base pairing forms a stable molecule for genetic information storage.

Therefore, based on function, without this molecule, genetic information would not be stored or transmitted.
