Unit 5 Test Review

What is the central dogma of biology?

• DNA -> RNA -> Cells

• DNA -> Protein -> RNA

• DNA -> RNA -> Protein

• Protein -> DNA -> RNA

In protein synthesis, which order is correct?

• mRNA is made in the nucleus, travels to the ribosome, pairs with tRNA, which makes bonds with amino acids

• mRNA is made in the ribosome, travels to the nucleus to pair up with DNA, and makes amino acids

• DNA in the nucleus leaves and goes to the ribosome to pair with RNA to make amino acids

How do you get the protein from fish when you eat it?

• Your body turns the fish protein into human protein you can use.

• Enzymes break down the protein into amino acids.

• The protein is immediately used once the fish is swallowed.

• The proteins must get folded and then your cells can use them.
