Question

who was credited for finding the shape of dna? hershey and chase oswald avery linus pauley watson and crick

Explanation:

The question is about the discovery of the DNA structure. Watson and Crick are credited with determining the double - helix shape of DNA. Hershey and Chase's work was on DNA as genetic material, Oswald Avery's work was on DNA as the transforming principle, and Linus Pauling (note: likely a typo as "Pauley" here) worked on protein structures. So the correct answer is Watson and Crick.

Answer:

D. Watson and Crick (assuming the last option is D, with the option text "Watson and Crick")
