what is the first step of protein synthesis?
1 answer
The first step of protein synthesis is transcription. During transcription, the DNA code is transcribed into a complementary messenger RNA (mRNA) molecule. This process occurs in the nucleus of eukaryotic cells, where the DNA unwinds and an enzyme called RNA polymerase binds to the promoter region of the gene. RNA polymerase then moves along the DNA strand, synthesizing a complementary mRNA molecule by adding nucleotides according to the base pairing rules (A pairs with U, G pairs with C).
