Why hnRNA is required to undergo splicing?

Posted by Divyanshu Bhandari 8 years, 5 months ago

CBSE > Class 12 > Biology

2 answers

Sonakshi Kumari 8 years, 5 months ago

Due to presence of introns in hnRNA translation process is not processed properly so spilicing is important to occur.

1Thank You

Amar Kumar 8 years, 5 months ago

Splicing is a modification of an RNA after transcription, in which introns are removed and exons are joined. hnRNA is required to undergo splicing because of the presence of introns (the non-coding sequences) in it. These need to be removed and the exons (the coding sequences) have to be joined in a specific sequence for translation to take place.
