EK Bio 1001-- another WTF

Ok, I just need someone to tell me I am not wrong--

Prokaryotes reproduce by binary fission and CANNOT do mitosis, right? I know for sure they can't do meiosis, but I'm getting conflicting answers regarding mitosis from online.

From EK Bio 1001, # 733:

"The researcher should see bacterial cells dividing(mitosis) in the blood."

Can someone confirm? If this is a mistake(which I think it is), they seriously fcked up, because this whole problem is based on the mitosis of bacteria.

Edited to add--
Wiki says: "However, prokaryotes cannot be properly said to undergo mitosis because they lack a nucleus and only have a single chromosome with no centromere."

So for the purpose of the MCAT, if asked if prokaryotes can do mitosis, we should say no? The word "properly" is a little ambiguous.

Bacterias have circular chromosomes. They simply unzip, replicate, and split into two. It is not FORMALLY described as mitosis, and should not be as such. It is, like you said, binary fission.

Thanks, seraph!!
