• TRUE

• FALSE

99.9% of DNA is in the nucleus, where is the other 0.1% and what does it code for?

• mitochondria, codes for unimportant genes

• golgi body, codes for proteins

• mitochondria, codes for genes that critical for survival

• golgi body, codes for unimportant genes

what are the 5 stages of gene expression?

what are some examples of post-translational modifications?

• methylation

• acetylation

• stabilization

• phosphorylation

what are the 6 sites that regulate gene expression?

transport out of the nucleus is:

• energy dependent and highly regulated

• non-energy dependent and not regulated

TIC (transcription initiation complex) binds to

• TATA

• coding region

• exon

• intron

what do transcriptional co-activators do

• bind DNA

• physically interact with transcription factors

• increase probability that the transcription factor will bind to the response element

• increase expression

what is an example of a transcriptional co-activator

• PPAR

• PGC-1y

• RE

• TATA

exercise is a strong stimulus that increases transcription

• true

• false
