How are nucleotides synthesized
WebOn average, most oligos are less than 60-mer in length. Since the way oligos are synthesized requires repetitive reaction cycles that add additional nucleotides, the … 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.
