Proteins destined for the nucleus contain a "nuclear
localization signal" or NLS. How does the the NLS direct the
protein to the nucleus?
Proteins that contain a NLS are allowed to freely diffuse into
the nucleus
Proteins that contain a NLS interact with a receptor on the
surface of the nuclear membrane
Proteins that contain a NLS interact with a transport system
that is powered by the hydrolysis of GTP
Proteins that contain a NLS are synthesized by ribosomes
attached...
2) Proteins imported to which of the following organelles do NOT
have their signal sequence cleaved?
A. Peroxisomes
B. Mitochondria
C. Endoplasmic reticulum
D. Proteins targeted to all of these organelles have their
signal sequences cleaved
Why do we have introns and what is the purpose of them?
Why do we waste energy making introns?
The question may be broad but it's something our professor asked
us. Thank you.
List some body proteins and their brief function?
What is protein sparing effect pg 54
There are different structures of protein. What is denaturation
of proteins, explain with an example. What happens to AA in the
denatured protein?
Digestion and absorption refer to the chart you have created on
ch 3. Remember each nutrient is digested in different digestive
areas by different enzymes and are broken down to diff end products
(broken down basically to what they are made of...

Protein targeting to ER & elsewhere; signal peptide &
signal recognition particle. Why are some proteins targeted to the
ER? Compare secreted proteins to integral membrane proteins.
