Webthey found that 1 GTP molecuIe was hydrolyzed during each elongation cycle. It was proposed that the energy released in the splitting of GTP was utilized to move mRNA with respect to the ribosome, a process which occurs during translocation of peptidyl-tRNA and requires the participation of EF-G (1). Web1 mrt. 2024 · Transcription uses a DNA strand to create a complementary RNA strand. Translation uses the mRNA product of transcription to form proteins.

WebDuring elongation, RNA polymerase "walks" along one strand of DNA, known as the template strand, in the 3' to 5' direction. For each nucleotide in the template, RNA polymerase adds a matching (complementary) RNA nucleotide to the 3' end of the RNA strand. [See the chemical reaction] WebElongation.
