(A) Lampbrush chromosomes
(B) Polytene chromosomes
(C) Allosomes
(D) Autosomes​

Answer 1

Answer:

(B)

Explanation:

polytene chromosomes

Answer 2

✍️Question:-

$\rule{400}{4}$

$\red\mapsto$ Balbiani rings are the structural feature of.

• Lampbrush chromosome
• polythene chromosome
• Allosomes
• Autosomes

✍️Answer:-

$\rule{400}{4}$

Option (B) Polytene chromosome $\huge\bold\red\checkmark$ is the correct answer.

$\red\hookrightarrow$ Reason:-

• Balbiani rings are the large puffed structure in polytene chromosome and have a large content of RNA and shows a high uptake and turnover of RNA precursor.

$\large {\underline {\underline {\sf {\purple{Additional}}}}}$

• During certain stages of development specific bands and inter band region are associated with them greatly increase in diameter and produce a structural called puffs or balbiani rings.
• puffs are believed to be produced due to uncoiling of chromatin fibers present in the concerned chromosome
• The puffs are sites of active RNA synthesis.
