DNA Replication

Okazaki fragments

Small fragments of DNA produced on the lagging strand during DNA replication, joined later by DNA ligase to form a complete strand.

primase

The enzyme that creates a short sequence of RNA to start DNA replication

DNA ligase

The enzyme which connects (GLUES) the individual okazaki fragments on the lagging strand by forming covalent bonds

leading strand

The newly forming daughter strand of DNA that is replicated in a continuous fashion; the daughter strand that is replicated in the same direction that parental DNA is unwinding. (The fast side)

double helix

The shape of DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape.

lagging strand

The strand that is synthesized in fragments using individual sections called Okazaki fragments

Semiconservative

describes method of DNA replication in which parental strands act as templates, and one strand is present in each new DNA molecule

SSBP

single strand binding proteins stabilize the molecule

DNA Replication

the process of making identical copies of DNA before cell division

helicase

An enzyme that unwinds the double helix of DNA and separates the DNA strands in preparation for DNA replication. (Unzips DNA)

DNA Polymerase

Enzyme that builds the complementary strand in DNA replication.

Which way does DNA polymerase move

From 3' to 5'

hydrogen bond

A weak chemical bond formed when the slightly positive hydrogen atom of a polar molecule is attracted to the slightly negative atom of another polar molecule. It holds the DNA molecules together.

replication fork

a Y-shaped point that results when the two strands of a DNA double helix separate so that the DNA molecule can be replicated
