Which of the following correctly identify the components of a nucleotide?

• A - Deoxyribose Sugar

  B - Phosphate

  C - Nitrogen Base

• A - Phosphate

  B - Deoxyribose Sugar

  C - Nitrogen Base

• A - Nitrogen Base

  B - Phosphate

  C - Deoxyribose Sugar

• A - Phosphate

  B - Nitrogen Base

  C - Deoxyribose Sugar

Differences in traits such as eye color and the ability to digest milk are determined by differences in -

• The sequence of nitrogen bases in the DNA molecule.

• The number of deoxyribose sugars in the DNA molecule.

• The location of the DNA in the cell.

• The type of phosphate group bound to the deoxyribose sugar in the DNA molecule.

What is the purpose of DNA replication during the S phase of the cell cycle?

• To produce energy for the cell.
• To repair damaged DNA strands.
• To ensure that each daughter cell receives an identical set of chromosomes.
• To initiate cell division.
