Question

What did Watson and Crick’s model of DNA show?

sugars and phosphates on the inside


nitrogenous bases on the outside


a single nucleotide strand twisted in a spiral


two nucleotide strands wound in a double helix

Answer 1

Franklin produced an image containing "two strands twisted with double helix and phosphate back bone with base pairs".

Watson and Crick taken the x-ray image created by Franklin which lead to discovery of accurate model of shape of DNA.

Answer 2

D.) Two nucleotide strands wound in a double helix.

Step-by-step explanation:

Their model shows that DNA is composed of two double strand of nucleotide which are twisted around each other and run in antiparallel direction. the phosphate group and pentose sugar are present on outside, while nitrogenous base is present on inside
