Question

questions 1 through 3 refer to the following. 1 mark for review which feature of model 1 best illustrates how biological information is coded in a dna molecule? a the 5 and 3 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 by the sequence of nitrogen - containing bases. The linear sequence of base pairs in a DNA molecule determines the genetic code, which is used to synthesize proteins and carry out cellular functions. The 5' and 3' ends, hydrogen - bond labeling, and bonds between sugar - phosphate groups are structural features but do not directly code biological information.

Answer:

D. The linear sequence of the base pairs
