I don't get why mitosis is wrong ??!!!

I don't get why mitosis is wrong ??!!!

mitosis involves break down of nuclear membrane in the prophase stage, prokaryotes don't have a nuclear membrane thats why mitosis is wrong

Because prokaryotes divide by binary fission not mitosis...

I think it won't be less than 35/40 for an A .

 

[scarface007]

I think it won't be less than 35/40 for an A .

thats too high, it would be 33 or 30 not any less

 

[xtremeforums]

The paper was pretty easy... with maybe one or two tricky questions.
I'm afraid the grade threshold would be high for this paper! Coz apparently alot of people found it easy...
Discussion after 24 hours!! Only then we'd know what the threshold would actually be

Paper was extremely easy, everything was direct and straight to the point.
