give ne an example of a specific human cell that leaves the cell cycle temporarily?
cells in G1 may temporarily or permanently leave the cell cycle
is this what yiu were looking for?
srry i ment you
I think the human oocytes leaves the cycle for a while
please explain why do you think the cell leaves the cycle and then returns?
because they need some chemical signals(eg hormones) to finish their division. that hapenns especifically whe women reach puberty.
Besides a cancer cell, give me an example of a specific human cell that is continually dividing and explain why they are continually dividing?
ephitelial cell and the leucocytes and the stem cells(the ones which produces erithocytes)
why does it keep dividing?
because of their short period of life and the continuous chemical signals which stimulate their division (this signalas are IL-!, IL-2, IL-4, erytropoyetin etc all depend of the kind of cell)
what's a defenition of cell cycle check point? and please explain.
that is a stage where the cell cheks its own DNA (G2 period) looking for some delectios, or mistakes before it divides
how do you know this? is your source reliable?
well it is written in any molecular biology textbook you can make sure by yourself
ok
if the DNA check point proteins are not functioning what might be the result to the cell?
if the DNA check point proteins were not working, the mistakes originated during the replication replication would produce mutations, and as you know the cell have mechanism to eliminate cell which ane not identical have you ever heard about apoptosis?
No
what is apoptosis?
is the process of programmed cell death
okay
what environment conditions cause mutations in the dna structure?
you mean citoplasmatic changes or enviromental conditions?
environmental conditions
ok chemicals such as Arsenic, Asbestos, Benzene, Bisphenol A (BPA), Chromium Hexavalent compounds, Dioxins, Formaldehyde, Polybrominated diphenylethers (PBDEs), Polycyclicaromatic hydrocarbons (PAHs), Vinyl Chloride etc
what would force a mistake in replication or a frameshift/ substitution to occur?
well Thanks for all your help
thanks to you for asking
your welcome, you really were a big help
