New cards

Replication Fork

The Y-shaped region where DNA is split into two strands during replication.

2
New cards

Helicase

An enzyme that unwinds the DNA double helix ahead of the replication fork.

3
New cards

Replication Bubble

A region where the DNA strands have separated and replication is occurring.

4
New cards

DNA Polymerase

An enzyme that synthesizes a new strand of DNA by adding nucleotides complementary to the template strand.

5
New cards

Ligase

An enzyme that fuses sugars and phosphates together on the new strand of DNA.

6
New cards

Nucleotides

The basic building blocks of DNA, composed of adenine, thymine, cytosine, and guanine.

7
New cards

Replication Levels

Multiple initiation points during DNA replication to increase the efficiency of copying long DNA molecules.

8
New cards

Adenine (A)

One of the four nucleotides in DNA, pairing with thymine.

9
New cards

Cytosine (C)

One of the four nucleotides in DNA, pairing with guanine.
