To create new cells
To repair damaged DNA
To produce energy for the cell
To pass on genes to new cells
Which of the following is true of DNA replication?
Each strand of DNA in the double helix serves as a pattern for duplicating the sequence of bases.
DNA replication creates new types of DNA molecules.
DNA replication ensures that each daughter cell has a complete set of genetic information.
DNA replication eliminates excess DNA from the cell.
DNA replication occurs in the mitochondria.
