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 and RNA also differ by the pentose sugars. RNA's pentose sugar is more oxidized (extra -OH group) and the DNA's pentose sugar is more reduced (-H instead). The same is also true of thymine and uracil. The extra -CH3 group on thymine of DNA is more reduced than the -H group on uracil of RNA. Two big differences between DNA and RNA that appear to reflect thse differences in reduction potential, are that the DNA always forms the double helix, while the RNA has more options. Secondly, the DNA is much larger than the RNA. Amazing what a little extra reduction or oxidation potential can do.

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 .

If we are to have extended duration of humans in space, they will be exposed to terrible radiation. A 6 month trip to Mars will seriously increase long term risk of cancer. However, there are plenty of organisms able to withstand much more radiation than humans. In theory, we can make a few small genetic modifications, and create humans able to live under this radiation indefinitely.

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.

If I was a dictator I wouldn't allow my experienced citizens to leave the country.

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.

Man is different from other life on this planet, is it possible that man is only part from this planet??????

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.

What about the wishes of the patient? Don't they count for anything?

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.

hey guys.. i was just wondering are there any methods, ways etc. to increase one's analysis and memory.. cause i can see that i am interllectually deteriorating..

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.

I'm a really big fan of the Harry Potter books but I just couldn't watch the films with out getting really annoyed with the acting.

Even though he's improved' date=' Daniel Radcliff is still a crap actor. He has this one expression where his mouth hangs open for every emotion in the film. The other two aren't as bad but they still ruin the film for me.[/quote']

ofcourse if u compare the movies and books it is definetly a disaster.actually the warner bros could write their own version of harry potter.
