Question

Puffs in polytene chromosomes are associated with:

A) Active translation
B) Chitin condensation
C) Tightly packaged DNA
D) Transcription
E) Carbohydrate modification

Answer 1

Puffs in polytene chromosomes are associated with transcription. These puffs represent areas of loosened chromatin where the DNA is accessible for gene expression.

Step-by-step explanation:

Puffs in polytene chromosomes are associated with: D) Transcription. In polytene chromosomes, puffs are regions that are actively being transcribed. These puffs represent areas of loosened chromatin where the DNA is accessible for gene expression. When a gene is being transcribed, the DNA in that region becomes unpacked and enables the transcription machinery to access the genes and produce RNA molecules.
