In humans, where does DNA replication (happen) take place?

• cytoplasm
• nucleus
• ribsomes
• vacuole

During replication, the function (job) of the enzyme DNA polymerase is to

• bind nucleotides together.
• send messages.
• receive messages.
• locate replication sites.

Choose the first three nucleotides of the complementary RNA strand. TAG

• AUT

During transcription, what does messenger RNA (mRNA) do?

• It delivers DNA's instructions for making proteins from the nucleus to the cytoplasm.
• It constructs proteins out of random amino acids inside the nucleus.
• It strings together two complementary DNA strands.
• It strings together two complementary RNA strands.

The central dogma states that information flows from

• RNA to DNA to polysaccharides.
• DNA to RNA to proteins.
