Question Detail
Question
Individual chromosomes are not visible at interphase because: a. they leave the nucleus and are dispersed to other parts of the cell b. they have uncoiled to form long, thin strands of chromatin c. the DNA has not been replicated d. sister chromatids do not pair up until division starts
Correct Answer
Option B is the correct answer.
Detailed Explanation
During interphase, chromosomes are in a less condensed, extended form called chromatin. This uncoiled state allows for DNA replication and transcription. They only condense into visible, discrete chromosomes as mitosis begins (prophase).
Hint
They are like long, thin, tangled threads, not compact rods.
