DNA Structure and Function practice

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme responsible for unzipping the DNA double helix during replication.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands that are complementary and anti-parallel.

Front

What are the base pairing rules in DNA?

Back

Adenine pairs with Thymine (A-T) and Guanine pairs with Cytosine (G-C).

Front

What does DNA stand for?

Back

DNA stands for Deoxyribonucleic Acid.

Front

What is the function of DNA?

Back

DNA stores and passes on genetic information.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide consists of a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases (adenine, thymine, guanine, or cytosine).

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the efficient storage of genetic information and the accurate replication of DNA.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA before cell division.
