How dna undergo transcription to makes rna
WebStep 1: Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases. WebThe copying of DNA to RNA is relatively straightforward, with one nucleotide being added to the mRNA strand for every nucleotide read in the DNA strand. The translation to protein is a bit more complex because three mRNA nucleotides correspond to one amino acid in the polypeptide sequence ( Figure 16.2 ).

WebMay 14, 2024 · DNA transcription of the genes for mRNA, rRNA, and tRNA produces large precursor molecules ( "primary transcripts") that must be processed within the nucleus to produce the functional molecules for export to the cytosol. Some of these processing steps are mediated by snRNAs. WebAug 22, 2024 · To initiate the process of transcription, the RNA polymerase must first identify the gene to be transcribed, the correct strand of the dsDNA that it must copy, and bind to a specific sequence on DNA called the promoter. A strand of DNA is read by the RNA polymerase in 3’-5’ direction and its RNA transcript is synthesized in the 5’-3’ direction.
