Questions and Answers

Which of the following is true about circ RNA?

It is circular in structure and difficult to degrade (correct)

It cannot modify miRNA and RNA lifetime

It cannot act as a tether and recruit other proteins/enzymes.

It is linear in structure and easy to degrade

What is the function of long non-coding RNA?

It can only regulate transcription.

It is not expressed in cells.

It can regulate transcription, splicing, and chromatin remodeling, and act as a tether and recruit other proteins/enzymes. (correct)

It cannot bind to DNA and RNA through base pairing.

Which of the following is true about X exsist and x i?

X exsist is irreversible during development or induced stem cells.

They are not involved in regulating the X chromosome

They have no involvement in sex determination.

They are terms used to describe the inactivated and processed X chromosome and are involved in sex determination. X exsist is reversible during development or induced stem cells. (correct)
