20. List the 3 basic steps of DNA replication: a. b. c. One of the strands comes from the original strand. When creating new cells, each cell needs DNA. DNA are the instructions for the cell - without DNA the cell would not function. DNA double helix, Chromosome, Nucleus Helicase opens up the helix.

explain how DNA is replicated accurately. explain how and why damage to DNA is repaired. Living cells must be able to duplicate their entire set of genetic instructions every time they divide. Likewise, multicellular organisms must be able to pass on complete copies of their genetic information to future generations.
cellular mechanisms—DNA replication and DNA repair—that are responsible for keeping these changes to a minimum. Finally, we consider some of the most intriguing ways in which DNA sequences are altered by cells, with a focus on DNA recombination and the movement of special DNA sequences in our chro-mosomes called transposable elements.
Before a cell can reproduce, it must first replicate , or make a copy of, its DNA. Where DNA replication occurs depends upon whether the cells is a prokaryote or a eukaryote.
accurate and complete replication of the DNA is essential to the ability of a cell organism to reproduce. In this chapter and the next, we will examine the process of replication. After describing the basic mechanism of DNA replication, we discuss the various techniques researchers have used to achieve a more complete understanding of replication.
DNA replication is the process in which DNA is copied. It occurs during the synthesis (S) phase of the eukaryotic cell cycle. DNA replication begins when an enzyme breaks the bonds between complementary bases in DNA. This exposes the bases inside the molecule so they can be “read” by another enzyme and used to build
