Structure of DNA

Front

What is DNA?

Back

DNA stands for deoxyribonucleic acid, which is the molecule that carries the genetic instructions for life.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the three components of a nucleotide?

Back

A nucleotide is made of a sugar (deoxyribose), a phosphate group, and a nitrogen base.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do nitrogen bases pair in DNA?

Back

Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the shape of the DNA molecule?

Back

The shape of the DNA molecule is a double helix.

Front

What is the role of the phosphate group in DNA?

Back

The phosphate group helps to form the backbone of the DNA structure.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information.

Front

What is a complementary DNA strand?

Back

A complementary DNA strand is the matching strand that pairs with the original DNA strand based on base pairing rules.

Front

If the DNA sequence is ATTGCC, what is the complementary strand?

Back

The complementary strand is TAACGG.
