WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. WebAug 9, 2024 · An important characteristic difference between RNA and DNA is the stability of their structures. DNA is a double-stranded helix shaped, like a twisted ladder, with two antiparallel strands that ...
