U4P1/2 Kozian DNA Structure and Replication

Front

What is DNA made of?

Back

DNA is a polymer made of monomers called nucleotides.

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each one with one new strand and one original strand.

Front

Why is DNA important?

Back

DNA serves as the blueprint for traits of all living things.

Front

What is the order of DNA replication?

Back

The order of replication is 3, 4, 1, 2.

Front

What base pairs with adenine (A) in DNA?

Back

Thymine (T) pairs with adenine (A).

Front

What base pairs with cytosine (C) in DNA?

Back

Guanine (G) pairs with cytosine (C).

Front

What are the components of a nucleotide?

Back

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

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix during replication.

Front

What is the function of DNA polymerase?

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 DNA?

Back

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