DNA Replication Review

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide consists of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What is the first step in DNA replication?

Back

The first step in DNA replication is to separate the two strands of the DNA helix.

Front

Where does DNA replication occur in a cell?

Back

DNA replication occurs in the nucleus of the cell.

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

If the original DNA strand has the base sequence ACCA, what will the complementary strand be?

Back

The complementary strand will be TGGT.

Front

What enzyme is responsible for unwinding the DNA double helix during replication?

Back

The enzyme responsible for unwinding the DNA double helix is helicase.

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.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' and 3' ends indicate the directionality of the DNA strand, which is important for replication and transcription.

Front

What is a replication fork?

Back

A replication fork is the area where the DNA double helix is unwound and replication occurs.

Front

What are Okazaki fragments?

Back

Okazaki fragments are short segments of DNA synthesized on the lagging strand during DNA replication.
