Why is control of genes expression necessary?
Regulation of gene expression is necessary because organisms need to be able to adapt to their environments and perform different functions.
2 types of operons?
The two types of operons are Inducible and Repressible Operons.
Does natural selection cause a change in the gene frequencies of the population over time?
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
What is the biggest change in evolution?
Probably evolutionary development, evo devo. This reanimated division of biology has shown us that the genetic endowment of organisms is remarkably the same, only differences in control and length of gene expression separates such widely variant organisms, such as flies and humans.
What is model organism?
Scientists select model organisms to understand that particular life form, and its interactions with other life forms and with the environment. They choose particular organisms as models, because of the hopefully wider applicability of the scientific findings. Scientists think that what they learn from the particular model organism will help them understand other organisms. The basic idea comes from Charles Darwin's On the origin of Species, and The descent of man. According to that idea, all living organisms track back to the same ancestor, or the same ancestral gene pool. In particular, model organisms are selected, to understand human disease. Often, it is considered unethical to use people to sort out possible causes of and treatments for disease. So, for example, causes of and treatments for cancer have been studied through the use of mice in laboratories.
Why is control of genes expression necessary?
Regulation of gene expression is necessary because organisms need to be able to adapt to their environments and perform different functions.
What is involved in regulating gene expression in prokaryotes but not in eukaryotes?
The regulation of gene expression allows prokaryotic cells, such as bacteria, to better respond to stimuli and to conserve energy and materials
Who was the operon model of the regulation of gene expression in bacteria was proposed by?
In 1961 Jacob and Monod proposed the operon model of gene regulation
Where might one go to learn more about gene regulation?
Wikipedia has many articles on the subject of gene regulation. One could also borrow or look up gene regulation in text books from their local library. Many university professors also post their lectures and notes on gene regulation online for everyone to view.
Why is gene regulation important in eukaryotes?
Gene regulation can occur in eukaryotic cells before, during, and after transcription.
What is unique about eukaryote gene regulation?
I dont knowww!!
What does cellular differentiation depend on?
regulation of gene expression
What is the main purpose of gene regulation in eukaryotes?
everything
What has the author Bart Deplancke written?
