Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which scientists were credited with discovering the structure of DNA?
A
Avery and Chargaff
B
Watson and Crick
C
Hershey and Chase
D
Mendel and Griffith
Explanation: 

Detailed explanation-1: -Scientists James Watson and Francis Crick were famously the first to work out the structure of DNA, and Rosalind Franklin and Maurice Wilkins are often credited for capturing the images of the molecule that made this possible.

Detailed explanation-2: -Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.

Detailed explanation-3: -The three-dimensional structure of DNA was first proposed by James Watson and Francis Crick in 1953. It is one of the most famous scientific discoveries of all time. X-ray diffraction of DNA crystals results in a cross shape on the X-ray film, which is typical of a molecule with a helix shape.

Detailed explanation-4: -Abstract. In 1962, James Watson, Francis Crick and Maurice Wilkins received the Nobel prize for the discovery of the structure of DNA. Notably absent from the podium was Rosalind Franklin, whose X-ray photographs of DNA contributed directly to the discovery of the double helix.
