DNA/Cloning

Front

What is DNA made of?

Back

DNA is a polymer made of nucleotides.

Front

What is a nitrogenous base with one ring?

Back

A nitrogenous base with one ring is called a pyrimidine.

Front

What forms the sides (backbone) of the DNA ladder?

Back

The sides of the DNA ladder are formed by deoxyribose sugar and phosphate.

Front

Who are the scientists credited with the double helix model of DNA?

Back

The scientists credited with the double helix model of DNA are Watson and Crick.

Front

What is a nitrogenous base with two rings?

Back

A nitrogenous base with two rings is called a purine.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix during replication.

Front

What is the significance of the phosphate group in DNA?

Back

The phosphate group is part of the backbone of DNA and helps to link nucleotides together.
