DNA Structure

Front

What is the structure of DNA?

Back

DNA is a double helix structure composed of two strands of nucleotides twisted around each other.

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

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What type of bond holds the two strands of DNA together?

Back

Hydrogen bonds hold the two strands of DNA together between the nitrogenous bases.

Front

Who discovered the structure of DNA?

Back

James Watson and Francis Crick are credited with discovering the structure of DNA.

Front

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

Back

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

Front

How many total nucleotides are in a DNA molecule with 5 base pairs?

Back

There are 10 total nucleotides in a DNA molecule with 5 base pairs.

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 nucleotide?

Back

A nucleotide is the basic unit of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
