What is Gel Electrophoresis?

Back

Gel Electrophoresis is a lab process that allows DNA analysts to separate and compare DNA samples for forensic purposes.

Front

What is a purine?

Back

A purine is a type of nitrogenous base that has a double ring structure. Examples include adenine and guanine.

Front

What is a pyrimidine?

Back

A pyrimidine is a type of nitrogenous base that has a single ring structure. Examples include thymine and cytosine.

Front

Which nitrogenous base pairs with guanine?

Back

Cytosine pairs with guanine in DNA.

Front

What is the complementary strand of DNA for ATGGC?

Back

The complementary strand for ATGGC is TACCG.

Front

What are the components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a deoxyribose sugar, and a nitrogenous base.

Front

What is the role of nitrogenous bases in DNA?

Back

Nitrogenous bases are responsible for encoding genetic information and pairing with complementary bases to form the DNA double helix.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, composed of two strands that wind around each other, with nitrogenous bases pairing in the center.

Front

What is the function of deoxyribose in DNA?

Back

Deoxyribose is the sugar component of DNA nucleotides, providing the backbone structure of the DNA molecule.

Front

What is the significance of the phosphate group in DNA?

Back

The phosphate group links nucleotides together, forming the backbone of the DNA strand.
