Abstemious_entity - How does this affect higher organisms? Its not a pathogen or virus thats killing these toads. It dont think it will affect anything higher than toads. The story is also here: m It seems that most people are going with the birds pecking at the toads and eating their liver, but i l...

Im fairly sure you'll find that the drug has an effect all over the body. Drugs like aspirin are so good because they have lots of targets. Drugs have a target, usually a cell surface receptor and if more of these receptors are found in the brain or head then thats where they will bind. Same with he...

I heard it was 100 miles long only joking. This is from Molecular Biology of the Cell (4th Edition) 2004. Alberts et al. Textbook. "Each human cell contains approximately 2 meters od DNA if stretched end-to-end" The differences may be in different cells/organisms. It looks like the high school teach...

My memory is a bit sketchy, but is it something to do with the fact that adenine and thymine are held together by two hydrogen bonds, but cytosine and guanine are held together by three hydrogen bodns and is therefore more stable? :?

Not really. Maybe. I thought maybe it would be more damaging for them as chemicals and smog could clog up the tiny holes of the insect. We just get respiratory problems like asthma but pollution may kill insects. Or they may get asthma as well and then we could make tiny inhalers for them Sorry. Rem...

No. Dont insescts, eg flies, breath through tiny holes in their skin? There must be some experiments or published data on the effects of smog/pollution on insects.

Acitve MPF is a kinase that phosphorylates Lamin proteins of the nuclear lamina, and promotes nuclear envelope breakdown. It also promotes mitotic spindle formation and chromosome condensation. Is that all you need for the first question? Im not sure about the other questions. This is not one of my ...

Im not sure about your second question, but i'll have a go at the first one This is a great website all about Myc which i am looking at now: m. I'll just copy stuff from there: The MYC cancer gene contains instructions for the production of the c-Myc protein. The c-Myc protein is now known as a tran...

Many animals display homosexuality. Theres even a book on it. m Ricky Gervais talks about this book on his Animals stand up comedy show (DVD). Thats where i heard about it. Its hilarious when he shows that the proof is drawings not photographs. Anyone can draw two homosexual animals. So, there may b...

Strange, ive never thought of it like what biostudent84 wrote. And i dont think many other people have. How does this work? People dont think "oh. theres too many people in this world, its overpopulated, i'll become a homosexual". Or is there a built in mechanism to make more people homosexual as th...

And thats news from 2001.

Edit: Just realised that you were talking about nucleus from another egg and not nucleus from any cell in the body. So i didnt really answer the right question. :oops: If you could put mitochondria in the egg then the energy issue wouldnt be a problem.
