When DNA is copied, the copying machinery in the cell is unable to start at the very end of the DNA molecule. Instead it must start (and finish) several 'words' into the long string of code. The new chromosome that results is therefore a tiny bit shorter at each end than the one it was copied from.

So how does the new cell manage without this bit of its genetic code? The way round the problem is that at the ends of the chromosomes there is a stretch of genetic code which is meaningless rubbish - code which is designed to be lost each time the cell reproduces. This is the telomere. The telomere consists of a sequence of 6 amino-acids, TTAGGG, repeated over and over again about 2,000 times. A few of these repeats are lost every time the chromosomes are copied when the cell divides. After a few hundred divisions, the telomeres are getting so short that there is a risk that meaningful genes will soon be missed off - vital code begins to fray. (In humans telomeres shorten by about 31 'letters' or amino-acids a year, more in some types of cell.) Eventually the ends of our chromosomes become so frayed that the cells are no longer able to reproduce themselves effectively, as new cells are formed without essential information and cannot survive.

This is why our cells age. With time cells and organs don't work as well as they should and the body starts to deteriorate, making it more vulnerable to disease. Through evolution our telomeres have developed to survive about 75 to 90 years of cell division. But telomere length is strongly inherited, which may explain why some families are long lived - these people may have longer telomeres than most.

That's why Dolly the sheep died so young, most sheep live for 12 years, Dolly's parent sheep was 6 when the DNA was taken and Dolly died of old age at 6, aging carries on through cloning.

In, the future, there will be hundreds of ice cream trucks holding undercover IRS agents. They pounce on anyone who has money to pay for the ice cream, cause by that time, the taxes are so high, that if anyone has money left for ice cream, the haven't paid their taxes.

In the future, there will be 100,000,000 TV channels.

But nothing to watch!! :evil:

[wormpaul]

We can watch al the "good" old stuff..

Like our childeren can watch again:

Allo Allo

A-Team

Tour of Duty

You gotta love that show. However if they make A-team The Nect Generation there's no chance of it being as good. So maybe that will be in the future too along with the end of the world.

I hear America were trying to teleport, wonder if they'll succed.

Depends on how far into the future.

Sometime in the next 50 - 100 years all firearms will be replaced with electric slug throwers. Low-orbit transport will replace airplanes as the method of choice for long-distance travel. The first attempts to explore Mars on foot will have just landed, to be met with what we've known all along: It's an inhospitibal hell hole. Terraforming reserch will then become the forefront reason for keeping NASA around. American and Russian relations will flounder as another Space Race begins, only to strengthen once again when all is said and done.

Planetside, cloning research will continue in secret as a method of attaining immortality by the world governments, while publicaly (sp?) they will all denounce it on various grounds, most of which will be rooted in religion. America will continue to bloat on it's own crapulence until eventually breaking up into numberous smaller nations after massive internal government fueding over personal politics. The entire world will continue to choak on coal and fossil fuel-based power while plasma, solar, and hydrogen-based fuels are developed and subsequently shot down as being innefectual and less effective. Cars will continue to become more and more powerful, while the drivers will remain the same, slow to respond and dim-witted. Eventually electrics will replace all fuel-based cars and any gas company that doesn't switch over will die. Along with this cars will leave their driver's control and become, in effect, track vehicles, following grooves in the road to their destinations, probably in long "trains".

I've got a lot more, but that's it for now.

@ xoopy

Ok....

The world is turning and so we centrifugate.

even if we could manage to make our dna stronger
we would still wear down after a couple of time :smoke:

there is no escape from death

except we could make the world not to turn anymore

"maybe" if you move more often to different places you might

not be affected by centrifugation so much :blink: :crazy:
