Protein Synthesis

This is a single strand of DNA, C C G T A C T . Choose the first three nucleotides of the other DNA strand.

• GGT

• CCT

• GGC

• TTA

The main difference between the four nucleotides that make up DNA is that they have different

• sugars

• uracil

• bonds

• bases

In humans, where does DNA replication take place?

• ribosomes

• nucleus

• ER

• cytoplasm

During replication, the function of the enzyme DNA polymerase is to

• bind the nucleotides together

• send messages

• receive messages

• locate replication sites

The single strand of DNA, T A G A G T C Choose the first three nucleotides of the complementary RNA strand.

• AUT

• CTA

• AUC

• ACG

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

• It delivers DNA's instructions for making proteins.

• It constructs proteins out of random amino acids.

• 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

• RNA to DNA to proteins

• DNA to polysaccharides to RNA

How many amino acids are coded for by the strand of mRNA, C G A U A C?

Where is messenger RNA (mRNA) "edited" into its final form?

• cytoplasm

• ribosomes

• nucleus

• anticodon

What is the process in this diagram?
