Question

1. a model of dna is shown. which part of the dna model is most directly associated with the coding of genetic information? 8. a student builds a model of a dna strand. which of these models of a dna strand shows bases that are complementary to the ones on the students dna model?

Explanation:

In DNA, the nitrogen - containing bases (represented by the gray rectangles in the model) are most directly associated with coding genetic information as different sequences of bases form genes. For complementary base - pairing in DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G).

Answer:

1. D
2. D
