Which statement best describes why the strength of the bond between the nitrogenous bases is so important?
DNA, found in every cell, stores and transmits genetic
information. DNA is made of long strands of nucleotides. Each
nucleotide is composed of a 5 carbon sugar, phosphate
group, and a nitrogenous base, as shown in the diagram.
O A. A strong bond twists the sugar-phosphate backbone of
DNA.
B. A strong bond keeps the double-helix structure of DNA
stable.
Nitrogenous
base
OC. A weak bond allows the two strands to separate easily
during replication
Phosphate
group
O
D. A weak bond allows for the separation of strands when they
come into contact with water, forming a solution.
