Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.

ATP is adenosine triphosphate, it is like a fully charged battery in a cell, ADP is basically ATP that has been drained of its energy from a chemical reaction. It is like a dead battery that can be recharged later ;)

Explanation:
<em>BRCA1 genes is a tumor supressor gene whose harmful mutation can cause hereditary breast ovarian cancer syndrome in both males and females. The BRCA actually stands for breast cancer.</em>
<em>Mutation in BRCA1 gene is heritable and every progeny of a carrier parent irrespective of the sex has a 50% chance of inheriting the trait from such parent, be it from the mother or the father.</em>
Hence, the correct option is a.
