The Structure of DNA

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What is a nucleotide composed of?

Back

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

Front

What is the role of DNA in living organisms?

Back

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

Front

How do DNA bases pair with each other?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the significance of the sequence of DNA nucleotides?

Back

The sequence of DNA nucleotides determines the genetic information and traits of an organism.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What enzyme is primarily responsible for DNA replication?

Back

DNA polymerase is the enzyme that synthesizes new DNA strands during replication.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double helix and separates the two strands of DNA.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is usually single-stranded.
