DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the purpose of DNA replication?

Back

To ensure that new cells have an identical copy of the DNA.

Front

What does 'semi-conservative' mean in the context of DNA replication?

Back

It refers to the method of replication where each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What role do enzymes play in DNA replication?

Back

Enzymes are necessary to unzip the DNA at the hydrogen bonds, allowing the strands to separate.

Front

During which phase of the cell cycle does DNA replication occur?

Back

DNA replication occurs during the S phase of the cell cycle.

Front

What are point mutations?

Back

Changes in a single nucleotide base pair in the DNA sequence.

Front

What are the three types of point mutations?

Back

Substitutions, additions, and deletions.

Front

What is a substitution mutation?

Back

A type of point mutation where one base is replaced by another.

Front

What is the significance of the S phase in the cell cycle?

Back

It is the phase where DNA replication occurs, ensuring each daughter cell receives a complete set of DNA.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.
