What is the relationship between DNA and proteins in all organisms?

• The nucleotide sequences contain the instructions used to synthesize

  amino acids.

• The amino acid sequences contain the instructions used to synthesize

  DNA and RNA.

• The helical shape of DNA resembles the helical shape of some

  proteins that are found in all cells.

• Cells are the same in all organisms, therefore there is no significant

  relationship between DNA and amino acids.

What woiuld happen if the active site for an enzyme gets blocked by poison?

• The enzyme would take longer to perform its normal functions

• The enzyme would be useless because its acvtive site was blocked

• the enzyme would transfer its active site to another location
