Created by StemPy LabTwo statements about interphase are given below. Statement I: In animal cells, DNA replication begins in the nucleus during S phase, and the centriole duplicates in the cytoplasm. Statement II: Cells that leave G1 and enter the quiescent stage (G0), such as the heart cells of adult animals, stop all their metabolic activity.

← A diploid cell with 2n = 14 has 2C of DNA in G1 phase. What does it have at the end of S phase?Match the stages of prophase I in List-I with the events in List-II.
List-I (Stage)
A. Zygotene
B. Pachytene
C. Diplotene
D. Diakinesis
List-II (Event)
I. The chiasmata terminalise, and the nucleolus disappears
II. Recombination nodules appear, and crossing over takes place
III. Homologous chromosomes pair, and the synaptonemal complex forms
IV. The synaptonemal complex dissolves, and X-shaped chiasmata are seen →
