Question

A strand of DNA contains the bases adenine, cytosine, cytosine, and guanine, in that order. What would be the order of the bases on the complementary strand of DNA?

Answer 1

Answer: Complementary strand of DNA will be thymine, Guanine,Guanine and cytosine.

Explanation: This is a process called DNA transcription, where DNA makes exact copies of itself during gene expression. DNA unwinds and parent DNA strand will make exact copies of itself resulting in two daughter strands. Complementary base pairs will be formed in a way that adenine pairs with thymine and guanine pairs with cytosine. This reaction is catalysed by DNA polymerase enzyme.
