Signal Transmission and Cell Function
100
Involves DNA regulatory sequences, regulatory genes, and small regulatory RNAs.
What is gene expression?
100
Turns on the expression of specific genes.
What is an inducer?
100
A complicated process in eukaryotes that involves regulatory genes, regulatory elements and transcription factors.
What is gene expression?
100
Regulates gene expression to allow for cell replication and division.
What is Cytokines?
100
Catalyzes the transfer of phosphate groups from ATP molecules to protein molecules.
What is protein kinase?
200
A sequence of DNA encoding a regulatory protein or RNA.
What is a regulatory gene?
200
Inhibits the expression of certain genes.
What is a repressor?
200
Transcription factors that increase expression.
What is an activator.
200
Allows fruits to ripen.
What is Ethylene?
200
Where signal transduction pathways operate.
What is the cytoplasm?
300
In DNA, where the regulation of gene expression normally happens.
What is transcription?
300
When regulatory proteins inhibit gene expression by binding to DNA and blocking transcription.
What is negative control?
300
Transcription factors that decrease expression.
What are repressors?
300
Substance whose levels regulate metabolic gene expression in bacteria.
What is cAMP?
300
Process that is especially dependent on signals sent between organisms.
What is mating?
400
The binding site of transcription-factors and involved in transcription by RNA Polymerase.
What is the TATA box?
400
When regulatory proteins stimulate gene expression by binding to DNA and stimulating transcription.
What is positive control?
400
The two main stages of gene expression.
What are transcription and translation?
400
A circuit that senses diverse external signals and causes responses such as changes in enzyme activity, gene expression, or ion-channel activity.
What is a signal-transduction cascade?
400
Groups of related genes that have the same function.
What is Hox genes?
500
A segment of DNA to which a transcription factor binds to regulate gene expression by repressing it.
What is an operator?
500
An example of genes that are continuously expressed.
What are ribosomal genes?
500
The stage of gene expression that can be regulated.
What is all stages of gene expression?
