b. Developmental structures
c. Phylogenetic trees
d. Structure and function charts
15. The following are components of Laemmli buffer
a. SDS, Bromophenol blue, 10x pbs
b. glycerol, SDS, Coomassie blue
c. Coomassie blue, 10x pbs, SDS
d. bromophenol blue, SDS, glycerol
16) What happens when myosin hydrolyzes ATP?
17. Which of the following gels are used to separate proteins –
a. polyacrylamide gels
b. agarose gels
c. both a and b
d. only a
Explanation / Answer
14. C
The similarities and differences in protein sequence help in establishing phylogenetic trees of different species. More similarities means more relatedness.
15. d
The buffer usually contains these three ingredients.
16. When myosin hydrolyzes ATP , there is displacement of myosin head along the actin filament. Release of Pi then causes the myosin head to bind to a new site on the actin filament.
17. a
Polyacrylamide gels are used for the separation of proteins effectively.
