Question

The point at which the polytene chromosomes appear to be attached together is known as

• A. Centriole
• B. Chromocentre
• C. Centromere
• D. Chromomere

Answer 1

Answer: (B)

Chromocentre

Chromocenter is the point at which polytene chromosomes appear to be attached together.

Centriole is paired cellular organelle which functions in the organisation of the mitotic spindle during cell division in eukaryotes.

Centromere is a specialised region on each chromatid to which kinetochores and sister chromatids attach.

Chromomere is a small beadlike structure visible on a chromosome during prophase of meiosis and mitosis.

Thus, the correct answer is option B.
