What: This occurrence bugs me. If the news reports are accurate, weeds are now becoming resistant to the herbicide Round up. This is similar to antibiotic resistance bacteria. In both situations you have selective poisons that work VERY well in the short term. But, over time, nature being what it is, a mutation pops up that causes these poisons to become ineffective. What you now have developed, unintentionally are super bugs and super weeds.

What: 'Outlining this behaviour earned two scientists a Nobel prize in 1965. "The lac operon is like the hydrogen atom of molecular biology, it's the first system that describes gene regulation," Xie says.'

What: "In the language of life, each of the ~23,000 genes/proteins encoded by the human genome is like a noun with its own special meaning. The possible interactions and functions of these proteins are akin to verbs. If we want to make real progress in understanding how cells work, a lot more researchers will need to markedly expand their biomolecular vocabularies. Otherwise, we will have a lot of data, but little knowledge."

What: "The recessive gene is like a white sheet of paper and the dominant is like a colored dye. The color will always show up, but the white cannot over power the color. If there are two whites however then the offspring will be white." Or maybe the dominant gene is like a bossy person.....see the link for the rest.

What: "They have most of their genes on a chromosome that is passed just to the descendents of each bacterium. But some genes are on a tiny loop of DNA called a plasmid that can leave one bacterium and enter another. If a chromosome is like a hard drive of genetic information, a plasmid is like a flash drive-tiny and portable."

What: "Regarding the case in Australia, if the compositions of matter being patented consisted only in Open Reading Frames (ORFs), then it would not be appropriate to characterize them as "genes." Genes contain regulatory sequences, such as promoters, methyl groups, enhancers, and introns. If the ORFs were substantially lacking in these things, or if the ORFs were completely lacking in these things, then it would be the case that the compositions of matter were far removed and distant from what occurs in nature. I am not sure why journalists insist on using the term "genes" to refer to Open Reading Frames. An Open Reading Frame is like a boat that is missing a hull. Because an Open Reading Frame, almost by definition lacks regulatory sequences, the Open Reading Frame would not be able to function properly in its natural environment"

What: "Vectors are like taxicabs that drive healthy DNA into cells; viruses, whose sole purpose is to get inside cells and infect them, make useful vectors." It's sorted like using a car to crash through a fence. ehh?
