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. WebDNA replication is an important process that occurs during cell division. It is also known as semi-conservative replication, during which DNA makes a copy of itself. DNA replication takes place in three stages: Step 1: Initiation The replication of DNA begins at a point known as the origin of replication.
