DNA Replication

the process of making identical copies of DNA before cell division

Specific sequence of DNA where DNA synthesis begins.

Each half of an original DNA molecule serves as a template for a new strand, and the two new DNA molecules each have one old and one new strand.

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

Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule

Sequence of RNA nucleotides bound to a region of single

the strand of DNA that is continuously synthesized into the replication fork.

The strand that is synthesized away from the replication fork , in fragments using sections called Okazaki fragments.

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

enzyme which connects the individual okazaki fragments on the lagging strand by forming covalent bonds

5' to 3' direction; In DNA synthesis, DNA strands always elongate in a 5' to 3' direction.

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

An enzyme that creates a short RNA primer for initiation of DNA replication.

A molecule that consists of nucleotide monomers used for transmitting genetic information from one generation to the next

Macromolecules that includes DNA and RNA.

A subunit of nucleic acids formed from a simple sugar, a phosphate group, and a nitrogenous base.

A nitrogen base found in DNA and RNA. It pairs with thymine in DNA and with uracil in RNA

A nitrogen base found in both DNA and RNA; pairs only with cytosine.

A nucleotide that pairs with adenine. Found only in DNA.

A nitrogenous base found in DNA and RNA; pairs with guanine

A weak chemical bond used to hold complementary base pairs together

Any of the pairs formed between complementary bases in the two nucleotide chains of DNA, such as A

Y shaped structure formed during DNA replication
