Biology and Chemistry Workshop
|
Date changed to Saturday 16 of october
What[edit]
This will be a beginners workshop, things I (U_go) want to cover :
- Biology for beginners
- focus on genetics
- theory on how to make GMOs
- also have fun with microscopes
- Chemistry for fun
- biology requires special stuff but we can have fun with some chemistry
- See Chemistry_experiments_1o1
Biology[edit]
- Introduction on cells
- Genetics, DNA and how it works
- Where to find DNA sequences
- How to program bacteria
- BioBricks
- Introduction on what to do next (get DNA, insert it in bacteria)
Who[edit]
- U_go

notes[edit]
___ Chemistry 1o1 ___
mendeliev's table of elements: http://www.ptable.com/?lang=us
neutrons change the weight, not the behavior
1 : nr of electrons in diff layers
1 : nr of protons H hydrogen : name 1.00794 : average mass
(as there is a some deuterium en tritium it is not equal to 1)
adding neutrons doesn't change behavior of atoms
2 : 2 electrons on first layer
1 : 1 electron on second layer
3 Li
what keeps an atom together? Strong nuclear force http://en.wikipedia.org/wiki/Strong_interaction
last column: noble gasses; inert left: akalines : release OH right:acids : release hydrogen
solvent :
brownian motion : particles moving because of temperature
C-N-O and H are basics for organic chemistry
Fe : used for instance in hemoglobine
Mg : eg in clorophyl
fun videos
each element comes with a very entertaining video that explains the
properties of the element.

___ Biology ___
dna is one molecule (in fact 2 molecules, each strand of the helix is one molecule)
dna is an acid and reacts well with base
4 bases {A,T,C,G}
A-T
C-G
sugars: cycle(s) with one oxygen and 4or5 carbon atoms etc saccharose
___ Genomes ___
3 main groups of organisms
- bacteria: difficult to see with microscope (eg diameter of red blood cell 7 micron, diameter of bacteria - 1 micron) - archaea (looks like bacteria, but with very different dna, living in very exotic environments - eg vulcanic lakes, ice etc) - eukaryota (complex cells, groups) plants, fungi, animals
bacteria - escherichia coli duplicates every 20min
cells in human body duplicate every 24h (eg skincells,..)
fly -- drosophila melanogaster -- small genome
yeast
13 Mbp (mega-base-pairs)
16 chromosomes
25% common genome with man
human 3Gbp
