Cards

Term
distal control elements
Definition
can be very far (10,000) from the gene that they affect 
Term
enhancer regions
Definition
binding sites for proteins like embryonic inducers or cytoplasmic determinants (a chemical that helps your body function)
Term
activators
Definition
two binding sites; one for the DNA and one for the protein sites of the activators to attach to the mediator proteins and general transcription factors 
Term
repressors
Definition
attach to the distal control elements blocking those sites from attaching to the activators. "silence" the gene. 
Term
prokaryotic transcription unit
Definition
operons
Term
euchromatin 
Definition
Control of chromatin structure in DNA; loosly packed; can be transcribed
Term
heterochromatin
Definition
control of chromatin structure in DNA; tightly packed; cannot be transcribed 
Term
to pack DNA
Definition
methylation of usually C nucleotides. 
Term
to unpack DNA
Definition
demethylate
Term
to pack histones
Definition
deacetylation 
Term
unpack histones
Definition
acetylate
Term
___________ are to distal control elements as ______ _______ ________ are to promoters
Definition
activators; general transcription factors 
Term
proteasome
Definition
protein eater. eats proteins that have ubiquitin attached. the ubiquitin is attached when the protein is no longer needed 
Term
upiquitin 
Definition
signal attached to proteins when they are no longer needed (will proceed to be degraded)
Term
non-coding RNA
Definition

inhibit translation

a) tRNA

b) rRNA

c) snRNA

d) microRNA (miRNA)

Term
George Santayana
Definition
"Those who do not remember history are doomed to repeat it."
Term
The Copernican Revolution
Definition
displaced people (earth) from the center and contracted biblical beliefs
Term
Thomas of Aquino
Definition
put an end to the dark ages (so called because there was very little learning of any kind) in western Europe by synthesizing. "The Great Synthesizer."
Term
sub-lunar
Definition
where humans were found/born; chaos 
Term
supro-lunar
Definition
moon and outwards; perfection
Term
Nicholas Copernicus 
Definition
said earth couldn't be the center, but didn't solve the problem completely because he still thought of circular movement when it was actually elliptical movement. Professor of the Roman Catholic faith. 
Term
Galileo 
Definition
Italian professor of mathematics; invented the first telescope; trained his telescope on the night sky and learned that the movement of sun spots showed that the sun was moving on its own axis 
Term
"Big Chill"
Definition
word spread through Europe and all controversial studies were ceased
Term
ramification of the trial of Galileo
Definition

1) Big Chill

2) shift in intellectual center of gravity to northern europe (Poland, Germany, Switzerland)

3) exodus of educated Roman Catholics from RC church to protestants (or atheists)

4) The Wedge; it became difficult for scientists and theologens to talk to each other
