Section 3: DNA Replication (study guide A)

DNA replication is the process by which DNA is (?) during the cell cycle.

DNA replication takes place in the (?) of a eukaryotic cell.

DNA is replicated during the (?) of the cell cycle.
S stage

DNA replication needs to occur so that every (?) will have a complete set of DNA following cell division.

A template is something that serves as a (?)

Suppose that one strand of DNA has the sequence TAGGTAC what sequence of the complementary DNA strand (?)

The 3 rules that proteins play during DNA replication.
~They help unzip the DNA strand.
~They hold the DNA strands apart.
~They bond nucleotides together.

In order for the DNA strands to separate, the (?) bonds connecting base pairs must be broken.

DNA replication is called semiconservative because each molecule consists of one (?) strand and one (?) strand.

The 3 steps of replication.
1) Enzymes unzip the helix.
2) DNA polymerase binds nucleotides together to form new strands that are complementary to the original strands.
3) Two identical DNA molecules result.

Human chromosomes have (?) origin(s) of replication, where the DNA is unzipped so replication can begin.

DNA polymerase has a proofreading function that enables it to detect (?) and correct them.

The suffix- ase indicates and enzyme. A polymer is a string of repeating structural units. DNA polymerase is an enzyme that makes DNA by forming bonds between (?)
