WebAnswer and Explanation: 1. Transcription always occurs in the 5' - 3' direction because it must be antiparallel to the complementary strand it is base paired with. So that means it will start at the 3' end of its complementary strand and proceed in the 5' - 3' direction as it copies the gene on DNA into mRNA. WebEukaryotic mRNA is read in the 3’ to 5’ direction. ... scientists have developed a procedure in which protoplasts of E. coli could be directly infected with the phage DNA.

During transcription, the RNA polymerase read the template DNA strand in the 3′→5′ direction, but the mRNA is formed in the 5′ to 3′ direction. The mRNA is single-stranded and therefore only contains three possible reading frames, of which only one is translated.
