Multiple choice

Translation of proteins from mRNA is characterised by formation of specific structures during the process. Which one is correct for polysome formation?

  1. Ribosomes with several subunits bind with Shine Dalgarno sequence.

  2. Several ribosomes are attached to a single mRNA during translation.

  3. Many ribosomes are attached to membrane of rough endoplasmic reticulum.

  4. Several subunits of ribosomes are attached with each other in a linear arrangement.

  5. Several 30S subunits are attached to mRNA.

B Correct answer
Explanation

During translation, several ribosomes are arranged in linear manner over a single mRNA. This is known as polysome. It helps in formation of globuler structure of proteins as many polypeptides are formed together.
