DNA translation is a term used to describe the process of protein synthesis by ribosomes in the cytoplasm or endoplasmic reticulum. The genetic information in DNA serves as the basis for the formation of messenger RNA (mRNA) through transcription. The single-stranded mRNA then acts as a template during translation.

Translation occurs in six phases: (i) binding of the mRNA to the ribosome, (ii) aminoacylation, (iii) initiation, (iv) extension, (v) termination and (vi) post-translational modification, (i) binding from the mRNA to the ribosome. I. Binding of mRNA to the ribosome.
Does DNA go through translation?
The process of copying DNA into RNA is called transcription, and the process of using RNA to make proteins is called translation. Each time a cell divides, each of its DNA double strands divides into two single strands. Each of these individual strands acts as a template for a new complementary DNA strand.
