DNA Structure and Replication

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is best described as a double helix.

Front

What are the three components of a nucleotide?

Back

The three components of a nucleotide are sugar, phosphate, and nitrogen base.

Front

What is the function of DNA Helicase?

Back

DNA Helicase is the enzyme that unwinds and unzips the DNA during replication.

Front

What is DNA made up of?

Back

DNA is made up of nucleotides.

Front

What is the result of DNA replication?

Back

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

Front

What is the role of DNA Polymerase?

Back

DNA Polymerase is the enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
