Question

Balbiani rings are found in
A. Polysomes
B. Polytene chromosomes
C. Autosomes
D. Note of the above

Answer 1

Hint:- The locations of specially active synthesis of RNA on the polytene chromosomes of dipteran chironomids tentans are known as Balbiani rings. These rings are named as Balbiani in the name of scientist, E.G. Balbiani in 1881. These rings are referred to as large chromosome puffs. Most of the time, Balbiani ring codes for vast amounts of protein existing in saliva are the major outputs of translation.

Complete Answer:-
The aggregation of various ribosomes that are involved in the procedure of energetically translating mRNA into protein is known as polysomes. About greater than one ribosome can translate an mRNA at one moment as it helps to generate numerous polypeptides simultaneously from a solitary mRNA.
Polytene chromosomes are large chromosomes which have thousands of DNA strands existing inside the salivary glands of insects and give a high level of the process there. Polytene chromosomes are formed in salivary glands of Drosophila, as the outcome of the replication of the chromosomes and the synapsis of homologues without division of cells. In between two bands in the staining procedure, the enlarged part of the polytene chromosome is present which is named as Balbiani rings. The huge chromosome puff present in the polytene chromosome is referred to as Balbiani rings.
Any of the numbered or non-sex chromosomes of organisms are known as autosomes. They occur in sets inside the somatic cells and individually in the gametic cells.
So, the right answer is Option B i.e. Polytene chromosomes.

Note:- The diffused and uncoiled area existing inside the polytene chromosome which is a site for transcription of RNA is known as chromosome puffs. The chromonema of the chromosomes divide but do not get segregated and therefore, persist together to evolve largely. The coiled central filament of a chromatid is known as chromonema.
