*DNA Structure, History, & Replication

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands of nucleotides twisted around each other.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the base pairing rule in DNA?

Back

A pairs with T, and C pairs with G.

Front

Where is DNA located in eukaryotic cells?

Back

In the nucleus.

Front

What is the process of DNA replication?

Back

The process by which DNA makes a copy of itself before cell division.

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix.

Front

What is the function of DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.

Front

What is a bacteriophage?

Back

A virus that infects bacteria, not human cells.

Front

What is the significance of the semi-conservative model of DNA replication?

Back

Each new DNA molecule consists of one old strand and one new strand.
