How are genes encoded
WebInstead, there is a sequential and parallel developmental process beginning at fertilization (earlier if you include parental epigenetic modifications) - encoded and regulated by 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.
