Question

In the cytoplasm we can find ___________________ U rich snRNA.

(a) U3, U4 and U6

(b) U4, U6

(c) U4, U5, U6

(d) U3, U5

This question was posed to me by my college director while I was bunking the class.

This interesting question is from Post-Transcriptional Modification in section Gene Expression : Transcription Prokaryotes of Cytogenetics

Answer 1

Right option is (b) U4, U6

The explanation is: U4 and U6 snRNA are found in the cytoplasm. They can associate to form a common RNP with the other proteins when they can move to the nucleus. In the nucleus, it interacts with U5 to form the tripartite complex.
