WebFeb 5, 2024 · The level of PER protein follows a 24-h cycle, increasing at night and decreasing during the day. (1) The PER protein is produced from the period gene at night. (2) In the cytoplasm, the PER protein pairs with the TIM protein, allowing it to enter the nucleus. (3) When inside the nucleus, PER inhibits its own production. WebThe nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
