DNA Structure

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands that wind around each other, consisting of nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the complementary base pairing rule in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

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 are the three components of a nucleotide?

Back

Sugar, phosphate, and nitrogen base.

Front

How do the strands of DNA run in relation to each other?

Back

The two strands of DNA run in opposite directions, known as antiparallel.

Front

What is the role of DNA in cells?

Back

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

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the efficient storage of genetic information and the accurate replication of DNA.

Front

What is the function of the sugar-phosphate backbone in DNA?

Back

The sugar-phosphate backbone provides structural support and stability to the DNA molecule.

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 instead of thymine.
