Ch. 12 and 13 Review

In humans, where does DNA replication take place?

• Cytoplasm

• Nucleus

• Ribosome

• Vacuole

A DNA nucleotide could contain the following molecules:

• deoxyribose, cytosine, and a lipid .

• deoxyribose, thymine, and a phosphate group.

• ribose, uracil, and a polypeptide. 

• ribose, adenine, and thymine

  In nucleotides, the letters A, G, C, and T represent

• phosphate groups. 

•                                             deoxyribose sugars. 

•              

  nitrogen bases.                                                 

•   ribose sugars.

The cellular process of creating two new DNA molecules from one original copy is called replication. Which statement is the BEST description of this process?

• DNA opens up and RNA copies it.

• DNA opens up and completely unwinds to make two new molecules.

• DNA opens up and each strand is used as a template for making a new strand.

• RNA opens up the DNA and uses each strand as a template for a new strand.
