A) It is no longer made B) It is actively chewed up by in the cell C) It is bound to other proteins like P16 D) None of the above E) A, B and C are all correct. Protons between the two membranes of the mitochondria A) Want to reenter the matrix B) Can be used to make ATP C) Can be used for transportation D) Can be used for other functions E) All are true Chromosome replication takes place during interphase. A) True B) False What is the Chromosome number during the second G_1 phase in Meiosis? A) 0 N B) 1 N C) 2 N D) 4 N E) 8 N What is the chromosome number after the S phase in mitosis? A) 0 N B) 1 N C) 2 N D) 4 N E) 8 N Recombination occurs in: A) Meiosis I S Phase B) Meiosis I Prophase C) Meiosis I Metaphase D) Meiosis II Prophase E) Meiosis II Anaphase The chromosomes that are separated in Mitosis are: A) Mother Chromosomes B) Daughter Chromosomes C) Identical (Sister) Chromosomes D) Homozygous Chromosomes E) None of the above The term for cell division is: A) Cytosis B) Karyokinesis C) Cytokinesis D) Plasmolysis E) Diviosis

Explanation / Answer

Answer:

Answer:

7). –

8). B. Can be used to make ATP

Explanation:

Proton gradient across the membrane of mitochondria helps in the synthesis of ATP.

9). A. True

Explanation: Chromosomal replication is otherwise called as DNA replication, which occurs in S-phase of Interphase.

10). B). 1N

Explanation:

After meiosis, chromosome number is reduced into half. So that the chromosome number in the second G1 phase is haploid.

11). C. 2N

Explanation:

During S-phase, DNA will be duplicated but there will be no change in the chromosome number. Hence, the ploidy of the cell will have no change.

12). B. Meiosis I Prophase

Explanation:

Recombination is nothing but the exchange of chromatids between the homologous chromosomes. This process occurs in the prophase of meiosis I.

13). C. Identical (sister) chromatids.

Explanation:

During mitosis, chromosomes do not separate instead sister chromatids will be separated. Then the each chromatid will develop into an individual chromosome.

14). C). Cytokinesis

Explanation:

Cyto=cell

Kinesis= division
