The parts of a gene that do NOT code for amino acids in a protein are called

• introns

• exons

• codons

• anticodons

The production of mature mRNA in eukaryotes involves

• cutting introns out and spicing exons together

• adding the 5' cap

• adding the 3' poly A tail

• all of these are correct

A protein that binds to the operator and blocks the RNA polymerase

• regulator

• repressor

• activator

• corepressor

The anticodon is located on 

• DNA

• mRNA

• tRNA

• rRNA

Which of these are involved in cutting out the introns? SELECT TWO.
