1. Suggest two ways in which, with the help of a microscope, one might determine the relative duration of the various phases of mitosis.
2. Describing the events and controls of the cell cycle is much easier if the cells under investigation are synchronous; that is, if a population of cells are all in the same stage of the cell cycle. This can be accomplished with various chemicals. But some populations of cells are naturally synchronous. The anther (male sex organ) of a lily plant contains cells that become pollen grains (male gametes). As anthers develop in the flower, their length correlates precisely with the stage of the meiotic cycle in those cells. These stages each take many days, so that an anther that is 1.5 millimeters long, for example, contains cells in early prophase I. How would you use lily anthers to investigate the roles of cyclins and Cdk’s in the meiotic cell cycle?
Here are the For Investigation questions for Chapter 9!
Question…Are we to do both questions or just pick one?
answer one question
Alright. Thanks!!!
This is not even on moodle so what are we supposed to do about it??
just write it up in a word document so you have it done whenever she does get it set up.
that's what i did!
which one are people doing?? i think i understand one more…
I went with number 1
go with the one the is most easy to you and only answer one
isnt the for investigation due this friday? the 5th? thats what it says on the moodle but I tried to submit an answer and it wont let me…
