Question

Capping and tailing are carried out on mRNAs to

• A. Ensure protection from ribonucleases
• B. Ensure attachment to ribosomes for translation
• C. Ensure ease of transportation and identification
• D. All of the above.

Answer 1

The correct option is D All of the above.

The nascent mRNA undergoes capping and tailing which protects it from the action of ribonucleases, helps in attachment to ribosomes for translation and also ensures ease of transportation and identification. This is basically a method of processing the mRNA before it proceeds into the cytoplasm for translation.
