A)pseudogenes code for proteins.
B)non-protein-coding DNA has no function.
C)non-protein-coding DNA may regulate gene expression.
D)pseudogenes have no function.

Question

Recent research has shown that non-protein-coding DNA can play a regulatory role in gene expression by coding for RNAs that affect transcription of coding regions. This indicates that non-protein-coding DNA may have a function in regulating gene expression. Pseudogenes, on the other hand, are non-functional copies of genes that do not code for proteins.
