Biology - March 2007

If a human is genetically altered in any form is it still human? I mean radical alterations with non-human dna, maybe of another genus. For example if I splice my children's dna with that of a cat, so they're somewhere between but still hold human attributes of speech and complex brain function, would they still be classified as human?

Is it possible that if a plant, say a maple tree, and an animal, say a cat, were spliced together that it would make a thinking tree? Is the biology of both too different that it would make it impossible? As in is it naturally impossible for plant based lifeforms to think?

I want scientific answers on what physically happens to our bodies when we die. And is there really such a thing called a 'soul' that lives within our physical bodies? Please explain this to me as best in scientific terms. What happens to that soul? Thanks.

Androgen Insensitivity Syndrome is also sometimes called testicular feminization. This is for a genetics paper I'm working on, and I know it's a frame shift or a point mutation on a gene that blocks it from binding to the androgen receptor, thus causing the female characteristics with the XY chromosome. But, I'm looking for something more in depth, and also the symptoms of this disorder. If anyone can provide any information in addition to the little that I already know, it would be much appreciated.

I mean, snap, what if people could instantly change their pigment levels? Would that change the opinions we have about it? There is biologically only one race of homosapiens, so rasism is a misnomer. Our preoccupation with coloring as humans is like someone walking into a florists shop and refusing to buy any roses with red petals, or yellow petals, or whatever because it can't be the same kind of rose.
No kidding?! You mean there's a variety of roses to chose from? Imagine that.

Hey Everyone! Biology Help Please! Ah..We are currently learning about DNA and I'm lost! I have till Thurs. to do this! I can't seem to find a good picture or explanation. Our Biology Book does not explain DNA in detail! I would like to know: How does DNA Replication occur or work? Steps?...And how do the terms DNA Polymerase, Okasaki Fragments, Leading and Lagging strand and DNA Ligase come into play with DNA Replication! Thanks:)

Please explain why....Bacillus spp. are usually thermoduric but not necessarily thermophilic, while other Bacillus spp. are both thermoduric and thermophilic

sorry couldnt fit the whole question...need answers ASAP!

I think that's how you spell it. anyway,

1) how many chromosomes do they have? if any...
2) do they require any oxygen (not neccessarily for breathing)?
3) can single celled organisms contract viruses?

seriously...
