DNA Replication Practice Flashcard

Front

What are the correct complementary base pairs in DNA?

Back

A - T and G - C.

Front

What sequence of DNA bases pairs with ATG TGA CAG?

Back

TAC ACT GTC.

Front

Why is DNA important?

Back

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

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, Guanine, Cytosine, Thymine.

Front

What does the semi-conservative model of DNA replication state?

Back

The daughter DNA molecule consists of 1 parent strand and 1 new strand.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

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 function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands.

Front

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

Back

The 5' end has a phosphate group, and the 3' end has a hydroxyl group, determining the direction of DNA synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.
