What is produced at the end of DNA replication?

• There is no goal.

• Two genetically identical sets of DNA.

• One set of DNA.

• Two genetically different sets of DNA.

What is the goal of DNA replication?

• There is no overall goal.

• To have 1 full set of DNA to divide between the 2 cells produced by cell division.

• To have a full set of DNA for each new cell produced from cell division.

• To have a full set of DNA for 1 cell only.

When does DNA replication happen?

• During the cell cycle.

• After the cell cycle.

• Once every year.

• Only during the development of the organism before birth.
