If you were to observe the activity of methylated DNA, you would expect it to

• be unwinding in preparation for protein synthesis.

• have turned off or slowed down the process of transcription.

Which enzyme was used to produce the molecule in the Figure?

• ligase

• a restriction enzyme

What is the enzymatic function of restriction enzymes?

• to cleave nucleic acids at specific sites

• to add new nucleotides to the growing strand of DNA

Restriction fragments of DNA are typically separated from one another by which process?

• gel electrophoresis

• PCR

Which of the following is true of DNA Replication?

• DNA is semi conservative because it creates two new strands of old nucleotide.

• New DNA strands are being synthesized in the 5' to 3' direction

• DNA is being synthesized in the 3' to 5' directions from a template strand

• RNA is being synthesized by RNA polymerase in the 5' to 3' direction

• A sense strand is created from a nonsense strand of DNA using RNA polymerase

Which of the following is a similarity between the process prokaryotic and eukaryotic organisms implement for protein synthesis?

• Transcription takes place in the nucleus, translation takes place in the cytoplasm

• Introns are removed by spliceosomes

• RNA processing adds a cap and tail to the mature RNA strand

• Transcription and translation happen simultaneously

• Ribosomes for phosphodiester bonds between amino acids
