MCBG Flashcards
1
Q
Where is rRNA found
A
In nucleolus
2
Q
Peroxisomes are for
A
Chemical detoxification
3
Q
RER role
A
Synthesis of proteins
4
Q
How many deoxyribose in DNA
A
2
5
Q
DNA polymerase works
A
3 - 5
6
Q
COOH is a proton
A
Donor
7
Q
Amino group is a
A
Proton acceptor
8
Q
increased CO2 causes
A
Increased CO2 causes PH to decrease, Bohr effect shifts curve right
9
Q
What is the donor molecule when an enzyme is phosphorylated
A
AMP
10
Q
Primary antibody in western blot binds to
A
A specific target protein
11
Q
Post translational modification of collagen
A
- O linked glycosylation takes place in Golgi
- Removal of amino acids from N and C terminus of procollagen in extracellular space outside fibroblast
- N linked glycosylation- glycosyl binds to asparagine
- O linked glycosylation- glycosyl binds to threonine and serine
- Serine, threonine and tyrosine can be phosphorylated
- N linked glycosylation in ER
- C chain cleaved off of insulin
12
Q
Nuclear envelope dissolves in
A
Prometaphase
13
Q
Transcription happens in
A
Nucleus
14
Q
Translation happens in
A
Cytosol
15
Q
chronic myeloid mutation in leukaemia caused by
A
Robertsonian mutation, non sense mutation = premature STOP codon
