Question

Identify the wrong pair of statements from the following.

(I) Cell organelles are newly formed in G${}_2$ phase of cell cycle.
(II) Doubling of DNA occurs in S phase of cell cycle.
(III) The nuclei formed after meiosis I are haploid.
(IV) Terminalization occurs in anaphase I.

• A. (I), (IV)
• B. (II), (IV)
• C. (III), (IV)
• D. (I), (III)

Answer 1

The correct option is A (I), (IV)

• Cell organelles are newly formed in $G_1$ phase of the cell cycle and get duplicated except the nucleus.
• Doubling of DNA occurs in s phase of the cell cycle.

• Nuclei that are formed after meiosis 1 are haploid because meiosis 1 is the reductional division it reduced ploidy from 2n to n.
• Terminalization occurs at the diakinesis stage which is part of prophase.

So, option A is correct.
