Only Add to 3' end
Cannot Start a strand
Can replace RNA w/ DNA |

Copy section of DNA, RNA Polymerase,Onestrand or other, with Sequences
Start- Promoter
Stop- Terminator
Messenger RNA mainly |
|
|
Term
| Messenger RNA (Transcription) |
|
Definition
1. cut and splice
introns- tossed(cut sections)
exons- splice together(remaining pieces)
2. Add 7- methyl guanosine 5' end
cap
helps attach to ribosome??
3. Add poly A tail 3' end
20-300( how many times you can use it)
lifespan message??? |

Last idea
3 letter words
4^3= 64 combinations
More than enough.
Each word
aa meaning(amino Acid)
several words same meaning
degeneracy
3 nt word= codon (are attached to messenger RNA)
Ribosome helps group letters |

Translate
1. Start
Groups 3nt
Start 5' >> first AUG
Methionine (f-met pro)
2. Stop
3 words= stop- no meaning
UAA, UGA, UAG
Need translator

Definition
Stable platform
Aligns
Links aa
sequence events
small ribo part links to mRNA
then
small links to large |
|
|
Term
|
Definition
Two sites
transfer RNA binds
2 aa linked(at this point)
cut off tRNA(is the to the connection)(connected via a Peptide bond)
move-next codon (stops at UAA which has no meaning) |

Definition
I P O z/y/a :Structural
--------//-------------/-------------/-------------------
I= gene codes for inhibitor/regulator
P- Promoter- polymerase binds
O- Operator- inhibitor binds
z/y/a- genes code for proteins/enzymes use lactose |

Term
Induction
always off, till turn on with inducer |
|
Definition
. Repressor always made
binds/unbinds operator
blocks transcription
2. Add inducer - lactose
binds to/ changes inhibitor
Not bind operator
site open>>>transcribe z/y/a
3. lactose used up
Inhibitor reappears/ binds O region
transcription stops. |
