Why only one ...

Question

Why only one strand of DNA is involved in mRNA formation ?

Open in App

Solution

DNA transcribe only one strand into mRNA for two reasons:

With two strands, ribosomal proteins cannot access promoter regions, where it decodificate (read the nitrogenous bases) transforming into keys to put amino acids in respective positions, constituting proteins.

RNAs have only one strand, differently of DNA, that need two strands to have stabilization.
