Genetic Engineering
|
The transfer of genetic information to an organism to introduce a desirable trait
|
|
Phenotypes
|
Physical traits of an organism, inheritable.
|
|
Genotypes:
|
The genetic makeup of an organism
|
|
Genetic information is on...
|
Chromosomes, genes make up chromosomes, code for one trait
|
|
Prokaryotic
|
“Simplest”forms of life, Bacteria Cyanobacteria, Lack complexity of Eukaryotes
|
|
Eukaryotic
|
More Organized and complex, Organelles- membrane bound structures such as Nucleus, chloroplasts, mitochondria
|
|
Mitosis
|
Cell division to produce identical daughter cells
|
|
Meiosis
|
Cell division to produce gametes, haploid cells
|
|
Totipotency
|
All cells contain same genetic information
|
|
DNA- review structure of molecule
|
|
|
Semi-conservative Replication
|
|
|
Transcription
|
Make mRNA from DNA
|
|
Translation
|
At Ribosomes, use tRNA to make protein- review processes
|
|
Control of Gene Expression- Transcription factors and enhancers, different types of promoters
|
Promoter regions of genes- Enhancers and Transcription factors
DNA coiling- exposing gene for transcription- histone proteins Micro RNA’s Differential Splicing Promoter regions of genes can determine whether or not a gene is activated Enhancers and Transcription factors Enhancers: regions of DNA to which transcription factors bind Transcription Factors are proteins Regulatory genes code for transcription factors that activate other genes Promoters can be constituative- always on Promoters can become active at stages of development Can become active under certain environmental conditions Can be useful for genetic engineering |
