choose one correct answer:
the following small G proteins are responsible for cytoskeleton regulation
1) RAS mitogen Easzzed
X :
2)RAN nubliaris transport
:
3)Elf2 : translacio
4)RHO/RAC activ cytosceleton:
Choose one correct answer:
Binding of cytosolic aconitase to the mRNA 5’ UTR region will cause..
X
1) its transcription
2)DNA replication
⑪
3) Inhibit mRNA transport
4) inhibits mRNA translation
5) promote mRNA transport
T
Key:
Diacyl- glycerol
1) is produced by phospholipase C -
&
2) may lead to the production of protein kinase C -
3) its chemical structure is similar to the tumorpromoter phorbolesterase -
4) activation of G protein results in the reduction of diacyl- glycerol levels.
Choose the one correct:
Chromatin change ~???!
X mitochondrial proliferation
1)
2) nucleosome elimination
3) microtubules degradation
