Artificial DNA


What madness creates artificial DNA?
The one that ignores what nature may say
Think Mr Science of what could befall
If what you do now rebounds on us all
You may think Earth secrets are a prize to take
But it's really a demon you shouldn't awake
And though noble intent should not be denied
What will it matter who is saved if all life dies?
You think you are clever, but really you're dumb
Nature after all, has seen so many species succumb
All that we may create originates of the Earth
And only she may determine its eventual worth
So go ahead and meddle in the codices of being
But if it all unravels its extinction we'll be seeing

Scientists have created the first synthetic chromosome for yeast in a landmark for biological engineering. Previously synthetic DNA has been designed and made for simpler organisms such as bacteria. As a form of life whose cells contain a nucleus, yeast is related to plants and animals and shares 2,000 genes with us. So the creation of the first of yeast's 16 chromosomes has been hailed as "a massive deal" in the emerging science of synthetic biology.

The genes in the original chromosome were replaced with synthetic versions and the finished manmade chromosome was then successfully integrated into a yeast cell. The new cell was then observed to reproduce, passing a key test of viability. Yeast is a favoured target for this research because of its well-established use in key industries such as brewing and baking and its potential for future industrial applications.

One company in California has already used synthetic biology to create a strain of yeast that can produce artemisinin, an ingredient for an anti-malarial drug. The synthesis of chromosome III in yeast was undertaken by an international team and the findings are published in the journal Science (yeast chromosomes are normally designated by Roman numerals).
