just a thought. when we talk about evolution we are saying that different forms evolved ( usually from one to another which is better adapted) by accumilating mutations because of various environmental stressors etc . now my question is if that is the case then why do we still see single celled life. why do we see apes, they should all have adapted to the environment and tried to change into humans right ?

actually don't be so happy, the virus is probably just dormant now. the mutation still persists. only some people are more suseptable than the others if it finds the right host like a hiv patient , the virus could actually mutate into a much powerful strain.it can burst out any time and yes we need to be prepared , but i'm not sure if we really are.

DNA occurs as a single strand as well . for example in parvovirus etc.

you don't want to do anything like that . i mean if the gene expression can somehow be altered in the embryonic stages then fine otherwise no.if your friend still wants them i suggest he/she better use contacts what difference does it make anyway.

i think it is definetly possible, that is if the dna is so exactly the same as ours.and if anybody is intrested in knowing about the work that is going on in this field i suggest you vist the site http://www.becominghuman.org. there is a beautiful documentary on the evolution of man.

then there would be numerical chromosomal abberations leadin to down's or turner syndrome and all that .

nice thought , but when we do that how do we know if there is going to be a side effect . for ex if we introduce a gene that does help us fight off the dangerous effects of radiation we might be altering some other genes , their trancription , some could be switched off as well. if we are altering the genome to our convinence we must remember we are playing with a 6 million year oldevolution process.

no, since clearly their genome would be quite different from each other.although the twins donot have an exactly similar kind of genetic makeup but most of it matches.

for any outbreak of viral disease three conditions are necessary to be considered a pandemic 1. the virus must be highly virulent. 2. must be resistant to action of human immune system 3. should be transmitted from human to human. thankfully bird flu could not suffice the third condition as of yet. so it is not a pandemic at present , but soon will be, if the virus mutates. there have been cases where the birdflu actually spread from a mother to her son the to his aunt but it stopped there stating the virus still dosen't have the capasity to jump from human to human.and as far as control is considered i don't think there is a vaccin as of yet.

i see even ur not in your country. ur in UK.may be u should come back first.

i think it is all up to the parents to decide.but i highly doubt if all will remain clean after that. it depends on the company the child will develope in the future.if all his friends smoke , he will also smoke , wether he is been given a vaccin or not.

ok, if man is from some other planet , where is it? our ancestors must also be there.but till now even if NASA comes up every other day with an evidence to prove that life exists on other planets , it is still a blunt subject. so till then let us believe that we are from here and continue the authority.

hey when a person is dying he acts funny, well it is not like he can correct his decission after doing them. it is life.not any kind of riff raff. "ok oops i'm sorry i didn't mean to die, now can u put me back together."

hi, asprin was chemically salicylic acid. it caused irritation in mouth and throat and used to upset stomach. actually for some it caused more trouble than curing pain. but today the available asprin is acetyl salicylic acid, it has fewer side effects.but even then it must not be used frequently.

of corse he is faking......atleast that's what i think

wait a minute when we talk about heavy metals why not consider silver and copper as well. people cook in copper vessels& eat in silver plates. why is the royal family not down with something as of yet.and by the way gol i like ur sense of humor. and probably gold will do enough damage if u wear it on like for a thousand years. which is not possible so need not worry.

hello, what exactly makes u think that.anyway just use ur brain constantly and eat a lot of almonds u will see a tremendous change in urself.

if u were a good swimmer and could even swim seas b'coz ur strong ,would u ever bother to learn how to build a boat.no . same thing with the dino's as well, they didn't need intelligence.the nature did not permit them to gain any ,and they did not try as well.

of course what are u waiting for?GET TESTED NOW!!!!!!!! CLEAR.don't neglect health.HIV infection is hard to detect in the early stages especially when it is latent.but u say 5 years right, and u donot have any significant health problems ,Even then if u ask me get tested..

when people ask for advice i definetly feel happy ,. if they know the answer and even then ask me for it i 'll think that they are trying to just verify it before they act.

i would go back to the era when people just started discovering genes and dna etc and then i would tell them what ever we know today about genetics and bag the noble prize . and do many more things then i would be like the founder of modern science.

i think it is so damn necessary to know who ur parents are. and this having a child without a man thing is so stupid . what is the fun....... all that impatient waiting of the man u love outside the labour room ,the first kiss of the father or the guy on the fore head of the baby are certain things which are necessary. they bring beauty to life.and the love comes automatically if the guy is the true father.

i would not let the person die and let the doctor who was so immoral cure him/her. i mean after all he has done all that stuff to find a successful cure and when he finally did it why not appreciate the guy for that. i will not let someone loose their lives because of that. a strict no.

the laboratories dealing with such live viruses have of course the necessary precautions to prevent such a mishap. and by the way it is very important that we culture these viruses , for various reasons like for testing the virus to check its pathogenesity and things like that. all the viruses (which are deadly ) for that matter are cultured in labs. they need the stocks.
