What is DNA replication?
When a cell makes a full copy of DNA prior to division.
What is hydrogen bonds jobs?
to connect the two strands of DNA
What does DNA helicase do?
Separates DNA during replication and moves the replication fork forward.
What is the double helix?
The form of DNA, referring to its two strands wound into a spiral shape
How many steps are in DNA replication?
5 steps.
When does DNA replication occur?
DNA replication occurs during the S stage of interphase.
Why does DNA replication need to occur?
DNA replication needs to occur because existing cells need to divide to produce new cells.
Why is replication an essential process?
Whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA as the parent cell.
What is a complementary strand also known as?
A complementary strand also known as a lagging strand.
What is Transcription?
DNA is converted into RNA in the nucleus
What is the S phase?
The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
True or false: Three hydrogen bonds are used to pair C and G.
True.
Where does DNA replication occur?
DNA replication takes place in cytoplasm.
Suppose that one strand of DNA has the sequence TAG, what is the complementary strand?
ATC
What is a replication fork?
A Y-shaped region on a replicating DNA molecule where new strands are growing.
When was DNA replication discovered?
1935
