Non- Coding RNA Genes

Question 1

Transfer RNA (tRNA)

Answer 1

key for the translation of DNA to proteins.

Question 2

Ribosomal RNA (rRNA)

Answer 2

Important components of the ribosome, the translational machinery of the cell.

Question 3

Small Nucleolar RNA

Answer 3

Critical for rRNA processing in the nucleolus

Question 4

Small nuclear RNA

Answer 4

Critical components of the spliceosomes, the machinery involved in splicing the introns out of the pre-mRNA.

Question 5

MicroRNAs or Short Interfering RNAs

Answer 5

These small RNA molecules (~22 bases) can turn genes on or off, control gene expression, and are important in chromatin shape, cell division and development.

Question 6

Long non-coding RNAs

Answer 6

These are non-protein coding transcripts longer than 200 bp that also seem to have a role in the regulation of gene expression
