DNA History and Structure

Front

What is the enzyme that unzips the DNA to prepare for replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of DNA during replication.

Front

Which enzyme is responsible for adding nucleotides during DNA replication?

Back

DNA Polymerase is the enzyme that adds nucleotides to the growing DNA strand during replication.

Front

What shape did Watson and Crick suggest DNA has?

Back

Watson and Crick proposed that DNA has the shape of a double helix.

Front

Which base does Adenine bond with in DNA?

Back

Adenine bonds with Thymine in DNA.

Front

What sugar is found in RNA?

Back

RNA contains the sugar ribose.

Front

What are the building blocks of DNA?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

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 function of DNA Ligase?

Back

DNA Ligase is an enzyme that joins Okazaki fragments on the lagging strand during DNA replication.

Front

What is the role of Primase in DNA replication?

Back

Primase synthesizes a short RNA primer to provide a starting point for DNA synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is usually single-stranded.
