but haven't the chromosomes already been fully duplicated by anaphase? meaning there would be 16 of them? im probably wrong..it sucks when u think u know something and then u see a question about it and u realize u really don't!

it's definately 8. 4 in interphase which divide to 8. By anaphase these chromosomes are on the opposites polls of the cell. After Telophase you will have 2 cells each w/ 4 chromosemes (just like the original.)
Expect questions of this sort on the DAT.

Ok guys lets spice things up a bit 😀
Diploid number is 4 as above (2 homologous pairs)
And you want to know how many chromosomes are present in METAPHASE of mitosis.
Wouldn't you only have 4 since the sister chromatids are not seperated yet?
If i recall correctly a pair of sister chromatids can be called a chromosome or each sister chromatid can be called a chromosome.

I think you are right. During synthesis, the cell duplicates each chromosome, so that each chromosome has two chromatids. So 4 chromosomes would be made up of 8 chromatids. However, like you said, if they are still joined together, both chromatids are considered one chromosome. After separation, a total of 8 chromatids/8 chromosomes exist--four being pulled in one direction and four being pulled in the other direction. After cytokinesis, you would have two cells each with four chromosomes, which is the exact number you started with in the parent cell.

yes indeed. LOL

You mean you are a medical doctor and now you want to be a dentist? Well, the best way to study for the DAT is to get your hands on the blue Kaplan book and review all of the material. Then, if you find you are weak in a certain area you take a class, get a tutor, or self-study.

I bought it last week. I knew most of the stuff from SDN. If you want it to teach you how to excel on the DAT, don't, let kaplan do that. If you want it to tell you stuff about the admissions provess, only buy it if you are new to SDN and need a crash course in d-school admissions.
