The Watson and Crick Model Showed That in the DNA

Question

The Watson and Crick model showed that in the DNA molecule:
A)purines paired with pyrimidines,and the strands align anti-parallel to one another.
B)purines paired with purines,and the strands align parallel to one another.
C)purines paired with purines,and the strands align anti-parallel to one another.
D)purines paired with pyrimidines,and the strands align parallel to one another.
E)pyrimidines paired with pyrimidines,and the strands align parallel to one another.

Accepted Answer

The Watson and Crick model of DNA structure, proposed in 1953, demonstrated that in the DNA molecule, purines (adenine and guanine) pair with pyrimidines (thymine and cytosine), and the two strands of the DNA helix run in opposite directions, making them anti-parallel. This arrangement allows for the specific base pairing that is critical for DNA replication and function.
