GLOSSARY

	A ntisense RNA and DNA
	An approach for inhibiting functions of endogenous cellular genes which targets the gene"s messenger RNA rather than the gene itself. An RNA or single-stranded DNA molecule that is complementary (antisense) to the mRNA of the target gene is introduced into cells. This antisense molecule can base-pair with the mRNA preventing translation of the mRNA into protein.

	E nhancer
	Element is a cis-acting sequence that increases the utilization of (some) eukaryotic promoters and can function in either orientation and in any location (upstream or downstream) relative to the promoter.

	Exon
	A continuous coding segment of a eukaryotic gene. Many eukaryotic genes are "split" and have exons interspersed with nonsense DNA called introns. Thus, it is a part of the gene which encodes protein.

	I ntron
	DNA sequences in eukaryotes that lie within genes, but do not code for protein. In most instances, introns have no apparent function. Their presence "splits" the coding region of the gene into segments called exons. In the synthesis of messenger RNA, introns are copied into RNA, but they are removed by splicing, which restores the continuity of the coding sequence.

	P romoter
	Site on DNA where RNA polymerase binds and initiates transcription.

	Regulator
	Codes for an RNA or protein product whose function is to control the expression of other genes.

	Structural gene
	Codes for any RNA or protein product other than a regulator.

	T erminator
	A sequence of DNA, located at the end of the transcript, that causes RNA polymerase to terminate transcription.

	Transcription unit
	The region between the sites of initiation and termination by RNA polymerase.

	T ransposon
	Mobile genetic element that can change its position within or between cellular genomes.
