, a) G1 phase - 🧠ANSWER ✔✔cell is metabolically active and continuously

grows; no replication of DNA


b) S phase - 🧠ANSWER ✔✔DNA synthesis or replication takes place-->

amount of DNA doubles; centriole duplicates in cytoplasm of animal cells


c) G2 phase - 🧠ANSWER ✔✔protein synthesis


d) Go phase cells - 🧠ANSWER ✔✔Quiescent stage-exit from the cell cycle;

metabolically active however no longer proliferate


mitotic cell division in animals - 🧠ANSWER ✔✔in diploid somatic cells


mitosis - 🧠ANSWER ✔✔cell division in which the nucleus divides into

nuclei containing the same number of chromosomes (equational division)


4 stages of M phase - 🧠ANSWER ✔✔PMAT = prophase, metaphase,

anaphase, telophase


prophase - 🧠ANSWER ✔✔chromosomes become visible, nuclear envelop

dissolves, spindle forms, cell organelles disappear


metaphase - 🧠ANSWER ✔✔alignment of chromosomes on the metaphasic

plate;
