Five facts about prokaryotes
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. WebThe granulosa cells have a weak activity and the atretic follicles have an activity only a little stronger. The newly formed corpus luteum has little, but in a day or two it acquires a strong β-galactosidase activity, which persists until the death of the luteal cells. The interstitial cells also have as much as the luteal cells.
