The ability to produce all cell types, including all the specialised cells in an organismand extraembryonic cells.
Totipotency
1 of 11
The ability of a stem cell to produce all the specialised cells in an organism (but not extraembryonic cells as the genes of these cell types are not expressed and have become inactivated).
Pluripotency
2 of 11
An unspecialised cell that can develope into other types of cells and divide by mitosis to become new specialised cells.
Stem Cell
3 of 11
Factors that increase the rate of transcription.
Activators
4 of 11
Factors that decrease the rate of transcription.
Repressors
5 of 11
Code for useful proteins, such as enzymes.
Structural Genes
6 of 11
A DNA sequence located before th structural genes that RNA polymerase binds to.
Promoter
7 of 11
A DNA sequence that transcription factors bind to.
Operator
8 of 11
Codes for an activator or repressor.
Regulatory Gene
9 of 11
A bacterium that respires glucose, but it can use lactose if glucose isn't available.
