Group of ribosomes attached to mRNA

Question of The Day03-10-2023

A group of ribosomes attached to mRNA is known as: / एमआरएनए से जुड़े राइबोसोम के समूह को कहा जाता है:

Answer

Correct Answer : b ) polysomes / पॉलीसोम

Explanation :

A polyribosome (or polysome or ergosome) is a group of ribosomes bound to an mRNA molecule like “beads” on a “thread”.

It consists of a complex of an mRNA molecule and two or more ribosomes that act to translate mRNA instructions into polypeptides.

Originally coined "ergosomes" in 1963, they were further characterized by Jonathan Warner, Paul M. Knopf, and Alex Rich.

Hence, (b) is the correct answer.

पॉलीराइबोसोम (या पॉलीसोम या एर्गोसोम) राइबोसोम का एक समूह है जो एक "धागे" पर "मोतियों" की तरह एमआरएनए अणु से जुड़ा होता है।

इसमें एक एमआरएनए अणु और दो या दो से अधिक राइबोसोम का एक परिसर होता है जो एमआरएनए निर्देशों को पॉलीपेप्टाइड्स में ट्रांसलेट करने का कार्य करता है।

मूल रूप से "एर्गोसोम्स" को 1963 में गढ़ा गया था, उन्हें आगे जोनाथन वार्नर, पॉल एम. नोपफ और एलेक्स रिच द्वारा उल्लिखित किया गया था।

अतः, (b) सही उत्तर है।
