Question

Non-functional parts of heterogeneous nuclear RNA is
a) axon
b) introns
c) both
d) not

Answer 1

Non functional part of genetic material is - b) introns

•Gene contains promoter, condign region, non coding region and terminator sequence.

•Promoter is the binding site of RNA polymerase.

•Terminatior sequence codes to stop transcription.

•Coding region is known as Exon.

•Non coding region is known as intron.

•While translation into protein, introns are spliced away, to join exons to code for particular protein.

•Axon is nerve fibre cell, which conducts impulses or signals.

Answer 2

Non-Functional Parts( Introns

Explanation:

(b) introns  Is right answer which is Non functional parts of Nuclear RNA

1. Introns are The DNA encoding and non coding segment of a RNA transcript , that are joined out before the RNA particle is converted into a protein.
2. The exons are the area of DNA that code for proteins .
3. While introns don't encode protein items, they are vital to quality articulation guideline.
4. A few introns themselves encode utilitarian RNAs through further preparing in the wake of grafting to create non coding RNA atoms.
5. Elective joining is generally used to create numerous proteins from a solitary quality.
