DNA Structure

Front

What does DNA stand for?

Back

Deoxyribonucleic acid

Front

What shape does a DNA molecule take?

Back

Double helix

Front

Which bases pair together in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What are the three components of a nucleotide?

Back

Sugar, phosphate, and nitrogen base.

Front

What is the role of the sugar in a nucleotide?

Back

The sugar forms the backbone of the DNA structure and connects to the phosphate and nitrogen base.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information.

Front

What is a base pair in DNA?

Back

A base pair consists of two nitrogenous bases bonded together, forming the rungs of the DNA ladder.

Front

What is the significance of complementary base pairing?

Back

Complementary base pairing ensures accurate DNA replication and transcription.

Front

What is the difference between purines and pyrimidines?

Back

Purines (Adenine and Guanine) have a double-ring structure, while pyrimidines (Cytosine and Thymine) have a single-ring structure.

Front

What is the role of the phosphate group in a nucleotide?

Back

The phosphate group links the sugar of one nucleotide to the sugar of another, forming the DNA backbone.
