What determines the code, or information, of a DNA molecule?

DNA replication results in two DNA molecules,

• each one with two original strands

• each one with one new strand and one original strand

• each one with two new strands

• one with two new strands and the other with two original strands

When does DNA replication occur in the cell cycle?

• Before cell division

• After cell division

• When the cell divides

• Just before chromosomes separate

In order for DNA instructions to move from the nucleus to the ribosomes in the cytoplasm of a cell, an RNA copy of a DNA strand must be made. This process, which takes place in the cell nucleus, is called

• translation

• mutation

• DNA replication

• transcription

Interpret the graph

• Every amino acid will change in the protein sequence

• One amino acid will change in the protein sequence

• This is a frame-shift mutation

• This mutation will more than likely be deadly
