Adenine
A compound that is one of the four constituent bases of nucleic acids.
Chromosome
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells.
Cytosine
A compound found in living tissue as a constituent base of nucleic acids.
Gel Electrophoresis
A technique used to separate mixtures like DNA and proteins.
Guanine
One of the four constituent bases of nucleic acids.
Nucleotide
A compound consisting of a nucleoside linked to a phosphate group.
Thymine
A compound that is one of the four constituent bases of nucleic acids.
Restriction Fragment Length Polymorphisms (RFLPs)
A technique that exploits variations in homologous DNA sequences.
Restriction Enzyme
An enzyme produced chiefly by certain bacteria, having the property of cleaving DNA molecules at or near a specific sequence of bases.
