Transcription and Translation AP Biology

How do the three types of RNA work together?

• mRNA carries message, tRNA carries amino acids, and rRNA makes ribosome

• mRNA makes ribosomes, tRNA carries amino acids, and rRNA relays information

• mRNA carries amino acids, tRNA transfer message, and rRNA makes ribosome

• mRNA is made, tRNA holds the DNA in place, and rRNA removes the deoxyribose

What is the sequence of nucleotides on mRNA read in triplets called?

• anticodon

• codon

• triplet box

• wobble

Identify which molecules bind to the promoter region

• Ligase

• Topoisomerase

• DNA polymerase

• RNA polymerase

What is the flow of genetic information in cells from DNA to protein? (Central Dogma)

• RNA to DNA to protein

• DNA to RNA to protein

• protein to DNA to RNA

• RNA to protein to DNA

• GCU

• GCA

• UAA

• TAG

• UAC

• GTC

• CAG

A sequence of a DNA template strand is shown.

3' TCC AAT GGC TTA TTT 5'

Which of these is the correct amino acid chain produced from the DNA template strand?

• Arginine, Leucine, Proline, Asparagine

• Tryptophan, Phenylalanine, Leucine

• Serince, Leucine, Proline, Asparagine

RNA polymerase moves in which direction along the DNA?

• 5' to 3' 

• 3' to 5' along the template strand

• 3' to 5' along nontemplate(coding) strand

• 5' to 3' along the template strand

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

What is the function of the poly-A tail in mRNA?

• to add modified guanin to the 3' end of the mRNA

• to indicate the site of translational termination

• to code for the binding of RNA polymerase to the DNA

• to help protect the mRNA from degradation by hydrolytic enzymes 

Which of the following demonstrates base pairing rules to 5' - CAGGT - 3'

• 3' - TGGAC - 5'

• 3' - GTCCA - 5'

• 5' - GTCCA - 3'

• 5' - CAGGT - 3'
