List five types of cancer in which ncRNAs can be involved.
Imagine the four basic components of gene regulation are DNA, RNA, proteins, and small molecules. Which of these things can ncRNA interact with?
When an ncRNA functions as a decoy, ita. contains binding sites for many different proteins, therebypromoting the formation of a large complex.b. recognizes other ncRNAs and sequesters them, therebypreventing them from working.c. can alter its conformation, allowing it to switch betweenactive and inactivate conformations.d. may physically prevent or block a cellular process fromhappening.
