The processes of transcription and DNA replication are
fundamental to the metabolism of cells. Describe the major stages
of each of these two processes .Although very different in terms of
biochemistry they do have organizational features in common. In
your answer draw attention to some of these.
Note
Detail and comprehensive is explantation is required.
How are the processes of mitosis and meiosis different?
When are each occurring? What is the final product of each? How
does each process contribute to genetic variation that makes each
human a unique individual?
Consider the following reaction that is occurring inside a
sealed container:
CH4(g) + NH3(g) <-- --> HCN(g) +
3H2(g)
If we increase the volume of the sealed container without
changing the temperature, will this affect the amounts of product
and reactant in this container? If so, will the amounts of products
increase or decrease? Briefly EXPLAIN!
Recall the chemiosomotic synthesis of ATP occurring inside the
mitochondria. Would you expect to measure an electrical potential
across the inner membrane of the mitochondria when chemiosmosis is
active? Why or why not? If so, which compartment in the
mitochondria would have a more positive charge?
This question is relevant to molecular biology.
When the transcription machinery is compared between
prokaryotes and eukaryotes, one finds several similarities as well
as many differences. Focusing on each aspect listed below, explain
briefly key similarities and differences as specified. Use bullet
points to organize your answers and make them clear and
short.
Compare promoters in prokaryotes versus eukaryotes - what are
key similarities and important differences?
Compare the RNA polymerases in prokaryotes versus eukaryotes -
what are key similarities...
