In addition, when proteins are being made, the double helix unwinds to allow a single strand of DNA to serve as a template. This template strand is then transcribed into mRNA, which is a molecule that conveys vital instructions to the cell's protein-making machinery.
Explain how the structure of DNA, suggested by Watson and Crick, is a mechanism for how it replicates. The two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase.This enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.As DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix.his enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.
