Assertion : Synthesis of DNA takes place in the S-phase of interphase. Reason : Every chromosome, during metaphase has two chromatids.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion. A typical cell cycle comparises of interphase and mitotic phase (M-phase). The interphase comprises of first growth phase or \({G_1}\) phase, synthesis phase or S phase and second drowth phase or \({G_2}\) phase. The DNA synthesis occurs during S phase in the process of DNA replication. In the mitotic phase, each chromosome has two sister chromatids. The two sister chromatids are clearly visible during metaphase stage because the chromosomes are highly coiled. The two sister chromatids are joined at the centromere.

Morphology of chromosomes can be best studied at
1 Prophase
2 Metaphase
3 Anaphase
4 Telophase
Explanation:
During metaphase, condensation of chromosomes is complete and they can be observed clearly under the microscope. This then, is the stage at which morphology of chromosomes is most easily studied.

In which stage of cell division the chromosomes are most condensed :-
1 Prophase
2 Meta phase
3 Anaphase
4 Telophase
Explanation:
During metaphase, condensation of chromosomes is completed. They can now be observed clearly under the microscope after reaching their most condensed form.
