B

Bioinformatics

the use of computer technology to process a large amount of biological data

D

DNA microarray

a solid surface that has a microscopic grid of many DNA fragments, called probes, attached; used to determine gene expression

DNA Primer

a short single-stranded DNA sequence, easily synthesized in a laboratory, that is complementary to a sequence at one end of the target sequence

DNA Sequencing

a process in which the sequence of base pairs in a DNA strand is determined

E

Ethidium Bromide

a large molecule that resembles a base pair, which allows it to insert itself into DNA; used for staining electrophoresis gels

F

Functional Genomics

the study of the functions of genes, the proteins they make, and how these proteins function

G

Gel Electrophoresis

A method for separating large molecules, such as DNA, RNA, and proteins

M

Molecular Marker

a fragment of a known size that is run as a comparison standard for gel electrophoresis

P

Polymerase Chain Reaction (PCR)

a process that is used to make a huge number of copies of a DNA sequence in a laboratory, quickly and without the need for a host organism

S

Structural Genomics

the study of the structure of genes and their locations in a genome, as well as the analysis of the nucleotide sequences to locate genes within the genome
