Question

Riboswitches are located on mRNA DNA Ribosomes Both A and D can affect mRNA secondary structure and control translation initiation. aptamer DNA elF1 None of the above RNA polymerase can distinguish the noncoding regions from the coding regions. True False Genetic experiments have shown that base pairing between U1 snRNA and 5-splice site of mRNA precursor is Sufficient for binding Necessary but not sufficient for binding Unnecessary for binding Both A and C When does U6 snRNP associate with the 5end of the intron by base pairing through the U6 RNA? Occurs first prior to formation of lariat intermediate
