Question

Besides DNA and histone proteins, what other type of RNAs are a critical component of chromatin?

1) messenger
2) transfer
3) ribosomal
4) small nuclear

Answer 1

Small nuclear RNA (snRNA) is a critical RNA component of chromatin, involved in the processing of pre-mRNA during the maturation of mRNA.

Step-by-step explanation:

Regarding the critical components of chromatin beyond DNA and histone proteins, the other type of RNA involved is small nuclear RNA (snRNA). This type of RNA plays a key role in the splicing of pre-mRNA, which is an essential step in the maturation of messenger RNA prior to its translation into a protein. While messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA) are directly involved in the synthesis of proteins, snRNA is involved in the essential processing of mRNA.
