DNA Structure and Replication

Front

What is the structure of DNA?

Back

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

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the base pairing rule in DNA?

Back

The base pairing rule states that adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

How does DNA replicate?

Back

DNA replicates through a process called semi-conservative replication, where each strand serves as a template for a new complementary strand.

Front

What enzyme is responsible for unwinding the DNA double helix during replication?

Back

The enzyme responsible for unwinding the DNA double helix is helicase.

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 a mutation in DNA?

Back

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

Front

Why is DNA considered the blueprint of life?

Back

DNA is considered the blueprint of life because it contains the instructions for building and maintaining an organism's traits.

Front

What is the significance of complementary base pairing?

Back

Complementary base pairing ensures accurate DNA replication and the preservation of genetic information.
