Document Summary
Promoter a gene region, which contains a specific sequence of nucleotides, that lies. Sigma factor primarily responsible for recognizing the promoter sequence on the. Ribozymes catalytic rnas that speed up processes; found on the rough er and all. Ribosomes composed of several ribosomal proteins and ribosomal rnas; where. Exons the scattered pieces of coding sequences, also called expressed sequences; Introns long, noncoding, intervening sequences that are removed from the gene. Rna capping modifies the 5" end of the rna transcript, the end that is synthesized first. The rna is capped by the addition of an atypical nucleotide a guanine bearing a methyl group, which is attached to the 5" end of the rna in an unusual. Polyadenylation provides a newly transcribed mrna with a specific structure at its. In contrast with bacteria, where the 3" end of an mrna is simply the end of the chain synthesized by the rna polymerase, the 3" end of a forming eukaryotic.
