Ch. 13 Gene Expression

Front 1

A gene that codes for an (antisense) RNA that has a complementary sequence to an RNA that is its target.

Back 1

antisense gene

Front 2

The regulation of bacterial operons by controlling termination of transcription at a site located before the first structural gene.

Back 2

attenuation

Front 3

A terminator sequence at which attenuation occurs.

Back 3

attenuator

Front 4

The ability of a transgene (usually in plants) to inhibit expression of the corresponding endogenous gene.

Back 4

cosuppression

Front 5

The product that would result from translation of a short coding sequence used to regulate transcription of the tryptophan operon by controlling ribosome movement.

Back 5

leader peptide

Front 6

Very short RNAs that may regulate gene expression.

Back 6

microRNAs

Front 7

The inhibition of movement that occurs when a ribosome reaches a codon for which there is no corresponding charged aminoacyl-tRNA.

Back 7

ribosome stalling

Front 8

A catalytic RNA whose activity responds to a small ligand.

Back 8

riboswitch

Front 9

The technique in which double-strand RNA is introduced into cells to eliminate or reduce the activity of a target gene. It is caused by using sequences complementary to the double-stranded RNA sequences to trigger degradation of the mRNA of the gene.

Back 9

RNA interference (RNAi)

Front 10

The ability of a dsRNA to suppress expression of the corresponding gene systemically in a plant.

Back 10

RNA silencing

Front 11

A small bacterial RNA that functions as a regulator of gene expression.

Back 11

sRNA
