hi! need help with some questions....

Post by shiri » Thu Jun 22, 2006 7:03 am

yesterday I had the most frusrsting finels in cell biology...
It turns out that I had a few disagreements with the proffesor so I'm trying to prove her wrong and earn for some of us (students) points on the test....so here it is goes...

1. lysosome - the proteins that get there are:
a/ only the ones targeted with manose 6 phosphate
b/ are enzyme linked receptors that finish endocytosis

2. master genes...are they the ones who are responsible for making transcription factors? (from what I knew they are overseeing the regulatory genes - and they art the ones for trans.fact.)

3. which of the follwings are SSDBP (sequence specific DNA binding proteins):
DNA polymerase
reprssore on the operetor sequence

4. N-acetyl neuraminic acid - is it:
a/ an acid with a hydroxyl
b/ part of an oligosaccharide wich is conected to dolichole diphosophate

thanks for the help.....

The answer for question 3 is the repressor that binds the operator.

The lecturer probably wrote the test, the study material and all your (her) lecturers. I admire that you feel you are right and want to research this but odds are she is correct.
