Question

which of the following statements is/are true of long noncoding rnas? choose one or more: they can trigger the activity of histone acetyltransferases. they are involved in x chromosome inactivation. they can regulate the translation and stability of mrnas. they can silence genes by promoting the formation of euchromatin.

Explanation:

Long non - coding RNAs (lncRNAs) can interact with histone acetyltransferases to regulate gene expression. They play a role in X - chromosome inactivation, such as Xist RNA in mammals. LncRNAs can also influence the translation and stability of mRNAs through various mechanisms. However, they silence genes by promoting heterochromatin formation rather than euchromatin formation.

Answer:

They can trigger the activity of histone acetyltransferases., They are involved in X chromosome inactivation., They can regulate the translation and stability of mRNAs.
