Multiple Choice

During cell division, DNA coils tightly and assembles into visible structures known as:

centrosomes

ribosomes

chromosomes

nucleotides

Verified step by step guidance

Understand the context of the question: it asks about the structures formed when DNA coils tightly during cell division.

Recall that DNA in the nucleus is normally in a less condensed form called chromatin, which is not visible under a light microscope.

During cell division, chromatin condenses and coils tightly to form distinct, visible structures.

Identify the correct term for these visible, tightly coiled DNA structures as 'chromosomes'.

Differentiate chromosomes from other options: centrosomes are involved in spindle formation, ribosomes synthesize proteins, and nucleotides are the building blocks of DNA.
