| Description: An enzyme, RNA polymerase, uses one strand of DNA as a template to synthesize a pre-mRNA molecule. Transcription site fin. 3’ .B. a Growing RNA transcript (C) What happened in the gene region? RNA polymerase catalyzed the covalent bonding of many nucleotides to one another to form an RNA strand.The base sequence of the new RNA strand is complementary to the base sequence of its DNA template—a copy of the gene. @Csngegs Leem'ng. All Rams Reserved. UGAGGAGAAG pre-mRNA (d) At the end of the gene region, the last stretch of the new transcript unwinds and detaches from the DNA template (termination). 3, Picture Stats: Views: 179 Filesize: 147.62kB Height: 558 Width: 1500 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=44490 |
