[kyeongkong]

So the Campbell says it is metaphase but destroyer says it is prophase?

If you have Campbell Biology 8th edition, on page 233, under 'metaphase' it says it is the longest stage of mitosis and often lasts about 20 minutes.

Still prophase?

i think it should be prophase..think about it..during prophase nuclear envelope has to disappear, chromatin must condense into chromosomes and mitotic spindle has to form. that a lot of events that need to take place...as opposed to metaphase where chromosomes align and anaphase separate and telophase nuc.envelope reforms..even if i would have forgotten the answer that's the way i would reason this out.

so you guys think the book is wrong?

i think so..also if you do some research online you will find that prophase is indeed the longest phase of mitosis.

good catch though between ccampbell and destroyer!

Haha... well this is funny... it is 8th edition, and if it is so obvious that prophase is the longest, I don't know why the authors/editors wouldn't revise/edit that part of the book.. o well...

In the 9th edition this is removed.

No wonder ADA exam 2009 are full of errors, prob because how the ADA makes the exam corresponds to the Campbell book. lol

Is there a list of errors somewhere?

I meant a list of errors for 2009 ADA exam
