Any biology gurus here??

[kerryin2004]

I am in a cell bio class and I am having trouble with the following question...

What would be the most obvious outcome in terms of cell structure of repeated cell cycles consisting of only the s and m phases??


Any help would be greatly appreciated!

1. s&m would cause some minor bruising...

other than that I have no answer so forgive me for taking up space in your otherwise honorable thread...

3. glad to provide some joy...

others have provided me with so much...

Since the G1 and G2 phases are mostly about growth, each successive daughter cell would be half the size of the mother. It also might not allow duplication of the organelles if it is a eukaryotic cell.

5. Oh Crap!

I'm a practicing biologist and I can't answer that one. Then again I don't do cell work so I have an excuse I guess (hope). I'll look it up and see if I cna find your answer.

6. they'd keep getting smaller, for starters

you'd eventually run out of raw material and energy to synthesize new DNA, though, so... depends on how technically you want to read the question.

in a close approximation from the real world, you'd start getting more and more replication errors, chromosomal aberrations... basically, you'd have a tumor.

7. Thank you all!!

BTW I was hoping someone might know a good bio site to help me out.. I haven't been able to find one and I find my book to be lacking in information..

9. What textbook are you using?

What level class is this?

11. 2300

The book is essential cell bio, I cant find enough detail, but I cAN LOOK IN MY 1000 course book and find almost all the information..

12. I know how that goes

I still have my book from Bio 105/106 and I keep pulling it out because its diagrams are better than those in my genetics book. As for good websites, I don't know that many. I used the campbellbiology.com that was the supplement to the bio book I was telling you about, but you would have to buy a subscription.

8. memory is shot

m and s phase - not talking about cell division? PMAT?

You have my curiosity up - write back if you figure it out or give me more info, its been a long time.

10. PMAT is inside the M phase.

G1-growth
S -chromosomes duplicate
G2-more growth
M -all that good PMAT
Start all over again for the daughter cells.

14. aha!

thanks - its been a while (like 20 years)

Amazing all the stuff you can jam into your head and never use again!

13. Here's a related paper. Hope it helps.
