Explanation:
Detailed explanation-1: -The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5’ to 3’ direction, adding each new nucleotide to the 3’ end of the strand.
Detailed explanation-2: -First, the ribosome moves along the mRNA in the 5’-to-3’direction, which requires the elongation factor G, in a process called translocation.
