The stages of cell cycle during germ cell formation is-
(A). Meiosis I anaphase
(B). Meiosis II anaphase
(C). G1
(D). G2
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (C), (D), (A), (B)
(C) G1 — first. A germ cell first passes through interphase. In the G1 phase the cell grows and makes proteins, getting ready to copy its DNA in the S phase that follows.
(D) G2 — second. G2 comes after the S phase, when the DNA has already been copied. The cell makes the proteins needed for division. G2 is the last stage of interphase, just before meiosis begins.
(A) Meiosis I anaphase — third. In anaphase I the homologous chromosomes separate and move to opposite poles. This halves the chromosome number, so meiosis I is called the reductional division.
(B) Meiosis II anaphase — last. Meiosis II is like a mitosis. In its anaphase the sister chromatids separate. The division ends with four haploid cells, which form the gametes.
