DNA Structure and Function

Front

What are the three components of a nucleotide?

Back

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

Front

What is the backbone of DNA made of?

Back

The backbone of DNA is made of alternating sugar and phosphate groups.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A) in DNA.

Front

What base pairs with Cytosine in DNA?

Back

Guanine (G) pairs with Cytosine (C) in DNA.

Front

What is the sugar component of DNA?

Back

The sugar in DNA is deoxyribose.

Front

What type of bond holds the nitrogenous bases together in the DNA double helix?

Back

Hydrogen bonds hold the nitrogenous bases together in the DNA double helix.

Front

What is the structure of DNA described as?

Back

DNA is described as a double helix.

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

How many hydrogen bonds are formed between Adenine and Thymine?

Back

Two hydrogen bonds are formed between Adenine (A) and Thymine (T).
