Md. Scientists Build Bacterial Chromosome
By Rick WeissWashington Post Staff Writer Friday, January 25, 2008; Page A04
Scientists in Maryland yesterday said they had built from scratch an entire microbial chromosome, a loop of synthetic DNA carrying all the instructions that a simple cell needs to live and reproduce.
Venter said the goal is to design novel microbes whose handcrafted genomes endow them with the ability produce useful chemicals, including renewable synthetic fuels that could substitute for oil.
Critics, however, countered that without better oversight of the fledgling field, synthetic biology is more likely to lead to the creation of potent biological weapons and runaway microbes that could wreak environmental havoc.
Venter and others have already made synthetic genomes for viruses, which are about one-hundredth the size of bacterial genomes. Some activists contend that synthetic bacteria pose more dangers because, unlike viruses, they can replicate on their own and can survive a long time in the environment.
Venter said the work was green-lighted by government offices, the National Academies and an independent ethics review board.
What do you think about science being able to create life from nothing within a lab? Is it right or is it wrong?

DNA Extraction
Today we are going to do a DNA extraction lab, but yesterday you where able to do a virtual lab which walked you through the steps. So, what are the steps for DNA extraction?

Nondisjunction
Nondisjunction is when homologous chromosomes fail to separate properly during meiosis. What are some of the side affects of this occurring. Is there a way to detect this problem?
