LuciParticipantHi,
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!

A bacterial cell 🙂

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

with a cell wall ? 😉

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

no. No cell walls in fungi.

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

Why? Could you please explain a little. Thank you!

Why?"It refers to bacterial cell 🙂

Thus actually it says:
the cell has a cell wall and has no nucleus

Prokaryotic cell, that’s it 😉

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

murein and N-acetylglucosamine..:wink:
- February 2, 2006 at 7:14 pm #39335MrMisteryParticipant
Smarty guy hah?
Murein is a complex mix of a polisacharide and short peptidic molecules. The polisacharide is mande of 2 monosacharides: N-acetylglucosamine and N-acetyl muramicSo? 😉

hi, that might be prokarotic cell.your staining material denature the DNA that’s why it is collected.
- February 4, 2006 at 2:25 pm #39575Dr.SteinParticipant
Andrew: Cell wall material is not a problem in this case 😛
- February 4, 2006 at 5:29 pm #39641MrMisteryParticipant
victor corrected me when i said murein and i want to let him know i wasn’t wrong in saying so. And to show off a little 😆
- February 5, 2006 at 11:42 am #39696victorParticipant
haha….showing off is good sometimes..:lol:
