Inheritance of biological characteristics
Total genetics material of a single cell
Part of chromosomes that create a single enzyme/protein
Codes for One single amino acid--> triplet code(3 nucleic acid)- an orchestrator that tell them to all line up
Is the meaningful part of a strand(code)
A string in the chromosomes-->inter space-no contribution
Form codes--> remove intron from RNA-->create code or message
Distinctive genetic makeup of an organism
How the organism looks
One Chromosome -4288 genes--> we have 5 time that many genes
AT, CG- What is that?
The nucleic acid they make DNA
Purines and pyromidines
How DNA works during transcription
In a eukaryote, DNA never leaves the nucleus, so its information must be copied. This copying process is called transcription and the copy is mRNA. Transcription takes place in the cytoplasm (prokaryote) or in the nucleus (eukaryote).
The transcription is performed by an enzyme called RNA polymerase
Messanger RNA-caring template message
Transfer RNA-amino acid when needed
Ribosome RNA-places amino acid in sequence
Organic catalysts-make things happen
Makes process enzyme-on switch begins process
The on-off switch positive feedback-if lactose is present, it turns on the lactase gene--> so you can metabolize lactose
Most are fixed in the body-drop of genetic code 10 to the 10th power body fixes
Radiation-ultra violet sun rays- or I131-radiation
Cutting and pasting-fixing mutations to not get cancer
Genetic disorder where people can not repair mutations from the sun
What is the purpose of an Ames Test?
Salmonella bug developed to not fix mutations
Ex. Japan-What is rate of mutation->take DNA-> measure mutagens of environment
Mixing of DNA-not sexual, but an exchange of body fluids
Picks up loose DNA-get into cell
Contamination of DNA carried in by virus(bacteriophage)
"Jumping genes"-changing order of DNA
Sex in a group
Paternity,indentification, where you there?(Fingerprints or saliva)-->detective of pherensic
Yesterdays potatoes gone crazy
Specific nucleotide sequence-->tag with florescent tag
What is gene probe used for?
Quicker-->quick results can use antibiotics to treat actual problem
Take segment for missing gene put it into a cell of infant via a phage or take missing gene sequence w/friendly bacteria
engineer them to produce what we want them to produce.
Vaccines-passive or active
Blood clotting factors
Genetically altered organisms
Train bacteria to eat cancer cells
Stopping expression of bad gene that certain people are susceptible
Ex. Alzheimer--> operon suppression
Test of all of a person's DNA
