DNA Structure and Function Concepts

Front

Who named the shape of DNA 'double helix'?

Back

Watson & Crick

Front

What are the main differences between DNA and RNA?

Back

DNA is double stranded, has a different type of sugar (deoxyribose), and contains thymine instead of uracil.

Front

What enzyme is responsible for adding complementary base pairs during DNA replication?

Back

DNA polymerase

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is a double helix composed of two strands of nucleotides.

Front

Which enzyme unzips the DNA during replication?

Back

Helicase

Front

What are nucleotides made of?

Back

Nucleotides are made of a phosphate group, a sugar (deoxyribose in DNA), and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What base pairs with adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What is the role of primase in DNA replication?

Back

Primase synthesizes a short RNA primer to initiate DNA synthesis.

Front

What is the function of ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand during DNA replication.
