2E: Gene structure and regulation Flashcards
1
Q
structural gene and regulatory gene

The use of operons in gene regulation
A
- regulatory gene:
- promoter:
- operator:
- structural genes:

Q
A
6
Q
attenuation
A
in attenuation transcription of the trp structural genes begins but is stopped early beforee any actual proteins are made
7
Q
repressor gene
A
8
Q
regulatory gene
A
code for transcription factors (proteins)
* family of proteins that have a function (off and on)
9
Q
constitutive gene
A
10
Q
structural gene
A
genes that will code for a specfic protein (or in this case, enzyme)
11
Q
promoter
A
short DNA segment and the binding site for RNA polymerase
12
Q
operator
A
short DNA segmentt and the binding site of the transcrption factor (repressor in this case)
