DNA-cell question

Post by Luci » Sun Jan 29, 2006 7:07 pm

Hi,

I'm new into the study of Biology. Although confussed, I am motivated to learn.

Perhaps someone could help me to answer this question:

" Your friend asks you to view a microscope slide which has a cell that has a cell wall and an area of what appears to be DNA coiled in one region, but it is not bound by a distict nuclear membrane. he asks you what type of cell you think this is.
What would you tell him?
Why?"

Thank you very your help!

Luci

Other Than Bacteria. May be somatic Cell from female that has One x factor condensed (BAR BODY)

the answer is deffinetly bacteria. But could a fungi spore also fit in?

I take that back. they have cell walls, just different composition.

Thus actually it says:

the cell has a cell wall and has no nucleus

I realised that it had to be prokaryote cell last night when i was in bed. To lazy to wake up and turn the computer on.

Fungi have cell walls, but are not made of cellulose, they are made oh kitine. Bacterial cell walls are made of murein
