Bio after exam 3 ON FINAL

we need ? for gene expression

active protein

central dogma of biology

DNA to RNA to protein to active protein

3 types of controls

transcription control

translation level control

post translational control

transcription control

turn on or off transcription

translation level control

activation or deactivation or protein by binding to other active sites or repressor proteins, ph

example of post translational control

phosphorylation

lactose is a

sugar

lactose

dimen or glucose and galactose

operon

single promotor regulates multiple genes

makes mRNA with multiple genes (ORF)

ORF/ open reading frames

start and stop codon with multiple amino acids in the middle

Lac Z

beta galactosidase

chops lactose

Lac Y

Galactoside permease

transmembrane protein

symportor for H+ and lactose

types of secondary active transport

Lac A

Galactoside Acestylase

remove unwanted galactoside

Lac I

lac repressor

own promotes

not operation

always on and transcribing

when lac I doesn’t regulate

little bit of transcription

postive gene control

regulatory protein triggers transcription

negative gene control

regulatory protein shuts down transcription
