Current Question (ID: 12716)

Question:

Many ribosomes may associate with a single mRNA to form multiple copies of a polypeptide simultaneously. Such strings of ribosomes are termed as?

Options:

1. Polysome
2. Polyhedral bodies
3. Plastidome
4. Nucleosome

Solution:

Polysome or polyribosome is an aggregation or cluster of ribosomes attached with a single mRNA in order to produce multiple copies of the polypeptide chain by carrying on translation simultaneously. Plastidome is referred to as the plastids of a cell when they are referred to a functional unit. The nucleosome is the smallest structural component of chromatin and is produced through interactions between DNA and histone proteins. Polyhedral bodies in the cyanobacterium in some chemotrophic bacteria that fixed carbon dioxide—many of them are sulfur reducers or nitrogen fixers.
