Question

7 mark for review which feature of model 1 best illustrates how biological information is coded in a dna molecule? a the 5 and 3 labels at the ends of each strand b the labeling of the hydrogen bonds between base pairs c the lines connecting sugars and phosphate groups that represent covalent bonds d the linear sequence of the base pairs

Explanation:

Biological information in a DNA molecule is coded in the sequence of its nitrogen - containing base pairs. The order of adenine (A), thymine (T), guanine (G), and cytosine (C) along the DNA strand determines the genetic code. The 5' and 3' labels relate to the orientation of the strand, hydrogen bonds are important for base - pairing and stability, and covalent bonds between sugars and phosphates form the backbone, but none of these directly code the biological information.

Answer:

D. The linear sequence of the base pairs
