Adna molecule can be described as a twisted ladder. the form the sides, and the form the rungs. select one: a. sugar-phosphate chains; base pairs b. base pairs; sugar-phosphate chains c. sugars; phosphates d. sugars; base pairs

A. sugar-phosphate chains; base pairs

Further explanation

the representation of Deoxyribonucleic acid (DNA) is symbolic, not accurate, blueprint of life. The outside of the bent staircase consists of sugar and phosphate groups, while the rungs, or rungs, are formed by two nucleobases that are interconnected by hydrogen bonds.

DNA is a nucleic acid; along with proteins and carbohydrates, nucleic acids are essential macromolecules for all known living things. Most DNA molecules consist of two strands of biopolymers twisting each other to form a double helix. These two strands of DNA are known as polynucleotides because they consist of molecular units called nucleotides.

The two strands of DNA are anti-parallel, which means that the two are paired in opposite directions. Each sugar group is bound to one of four types of nucleobases. These sequences of four nucleobas along the back chain of DNA store the biological information code. Through a biochemical process called transcription, DNA strands are used as templates to make RNA strands. The RNA strand is then translated to determine the sequence of amino acids the protein is built on. In chromosomes, chromatin proteins such as histones play a role in the arrangement of DNA into compact structures
