QUESTION 20
Which amino acid(s) would you find in the core of a cytosolic protein?
Amino acids that make up the protein's signal sequence
Amino acids with hydrophobic backbones AND sidechains
Amino acids that have been phosphorylated on their side chains
The methionine found at the N-terminus of every protein
Amino acids with non-polar sidechains
QUESTION 21
Why is Ras such an important protein in the cell?
It produces secondary messengers
It opens ligand-gated ion channels
It binds to extracellular ligands
It switches on a cascade of kinases
It phosphorylates the mitogen activated protein kinase kinase kinase
QUESTION 22
Predict the effect of adding a microRNA that binds to the 3' UTR of insulin to a beta cell
The microRNA will interact with the insulin protein via hydrogen bonding
The microRNA will decrease expression of the insulin protein
The microRNA will block transcription of the insulin gene
The microRNA will regulate post-translational modifications of the insulin protein
The microRNA will prevent RNA polymerase from binding to insulin mRNA
