Translation is the first process in gene expression. It is defined as the process in which DNA molecule gets converted into RNA with the help of an enzyme known as RNA polymerase.
As we know that both RNA and DNA are polymers of nucleic acids. In this process, they both use base pairs of nucleotides with complementary bases.
