CP DNA Structure and Replication

Front

What are nucleotides composed of?

Back

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

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, resembling a twisted ladder.

Front

What are the base pair rules in DNA?

Back

The base pair rules in DNA are A-T (adenine-thymine) and C-G (cytosine-guanine).

Front

What happens during DNA replication?

Back

During DNA replication, the DNA molecule unzips, and each strand serves as a template for the formation of a new complementary strand.

Front

What is the first step in DNA replication?

Back

The first step in DNA replication is the unzipping of the DNA molecule.

Front

What is the role of the sugar in nucleotides?

Back

The sugar in nucleotides (deoxyribose in DNA) forms the backbone of the DNA structure, linking with phosphate groups.

Front

What is the significance of the phosphate group in nucleotides?

Back

The phosphate group connects the sugar of one nucleotide to the sugar of another, forming the DNA backbone.

Front

How many strands does a DNA molecule have?

Back

A DNA molecule has two strands that run in opposite directions.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What is a mutation?

Back

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