Consider the given two statements:

l. During G1 phase the cell is metabolically active and continuously grows but does not replicate its DNA.

ll. During G2 phase, proteins are synthesized in preparation for mitosis while cell growth continues.

Of the two statements:

2. Only ll is correct
3. Both l and ll are correct
4. Both l and ll are incorrect

How do cells at the completion of meiosis compare with cells that have replicated their DNA and are just about to begin meiosis?
1. They have twice the amount of cytoplasm and half the amount of DNA.
2. THey have half the number of chromosomes and half the amount DNA.
3. They have the same number of chromosomes and half the amount of DNA.
4. They have half the number of chromosomes and one-fourth the amount of DNA.
