The cell cycle includes the G1 (presynthetic) phase for organelle creation, the S phase for DNA replication, and the G2 (postsynthetic) phase for checking organelles and DNA. The G2/M checkpoint ensures sufficient cell size and proper DNA replication, involving the p53 protein.
Le fasi del ciclo cellulare sono G1 (presintetica, creazione di organelli), S (sintesi del DNA, replicazione del DNA) e G2 (post-sintetica, controllo degli organelli e del DNA). Il checkpoint G2/M verifica le dimensioni cellulari e la corretta replicazione del DNA, con il ruolo della proteina p53.
| Text | Cell Cycle: Presynthetic gap::G1 - creating organelles Phase Postsynthetic gap::G2 - check to make sure there are enough organelles/cytoplasm and DNA replicated correctly Phase G2/M::cell checks to make sure it is large enough and has been properly replicated, p53 plays a role checkpoint restriction point::must be passed to reach next stage of cell cycle |
