Material for the intro that should be re-written using layman terms associated with the corresponding functions (transport, antennas, signals, receptors, transmitters, gates, etc). Select the graphic images that are easier to describe in layman terms.
[Note that a big chunk of the material that was here has been moved to separate documents -in the shared drive- for review.]
This video is taught at the high school level. This video disucsses the history of cell, the Cell Theory, cell diversity, eukaryotes vs prokaryotes, and endosymbiosis. I use this PowerPoint in my biology class at Beverly Hills High School.
ONCE, it all seemed so beautifully simple. Our DNA, we thought, consisted of a set of recipes, or genes, for making proteins, and once we had identified them all and worked out what they do, we would be a long way towards understanding what makes us what we are.
in many other ways our genome is turning out to be dizzyingly complex
“It is very difficult to wrap your head around how big the genome is and how complicated,” says Ewan Birney of the European Bioinformatics Institute near Cambridge, UK, who is part of a major project to uncover the workings of the genome. “It’s very confusing and intimidating.”
For starters, rather than each gene coding for one protein, they often code for many. The coding parts of genes come in pieces, like beads on a string, and by splicing out different beads, or exons, after RNA copies are made, a single gene can potentially code for tens of thousands of different proteins, although the average is about five. Recent studies suggest up to 95 per cent of our genes may be alternatively spliced in this way. Even more astonishingly, in at least one case in humans, RNA copies of different genes are spliced together. If this is commonplace, it would vastly …
While the amount of information is growing exponentially, our understanding of it is not keeping pace. “The sequencing is going faster than we have people to analyse the data,” says anthropologist John Hawks of the University of Wisconsin-Madison.
