A weak chemical bond used to hold complementary base pairs together

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

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

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

Any of the pairs formed between complementary bases in the two nucleotide chains of DNA, such as A-T and C-G (DNA); A-U and C-G (RNA)

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

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

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

the process of making identical copies of DNA before cell division

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

Sequence of RNA nucleotides bound to a region of single-stranded DNA to initiate DNA replication.

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

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

A Y-shaped region on a replicating DNA molecule where new strands are growing.

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

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

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