Describe how gene regulation occurs in bacterial cells?
Escherichi coli (E. coli) bacteria provide a good example of gene regulation - E. coli bacteria are genetically encoded to regulate production of enzymes that digest lactose only when lactose is present and no glucose is available.
In the control of gene expression in bacteria a regulatory gene a has its own promoter?
No
Deletion is when a whole segment of a gene is?
Deletion occurs when a whole segment of a gene is lost.
Gene cloning can involve inserting genes into?
bacteria
What are the transgenic bacteria?
Trangenic bacteria are bacterial colonies which are genetically modified by deleting or adding a particular gene sequence.

No
How many DNA are there in a gene?
In bacteria, the average length of gene is 1kilo bases
Deletion is when a whole segment of a gene is?
Deletion occurs when a whole segment of a gene is lost.

bacteria
What is the process of bacteria in genetically modified foods?
Bacteria is often the organism a gene is removed from. The gene is inserted into another species, often corn, soy, papaya, canola, etc.
Explain what benefits bacteria obtain from conjugation?
Bacteria only contain one copy of gene per cell. So the chances of the bacteria to survive with a random mutation is little to nothing. Conjugation (the exchange of genetic material between bacteria) allows for the bacteria cell to make this correction to the mutated gene.
Do most heritable differences are due to gene shuffling that occurs during the production of gametes?
gene shuffling
Why does the rapid reproduction of bacteria make them a good choice for cloning a foreign gene?
Because bacteria is speshal..:)
Antibiotic in gene cloning?
If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.
What are the steps to Genetically modified organism?
first you have to take the gene of interest (the gene that you want to put into the bacteria) and get it cut with restriction enzymes. then mix it with the plasmids from the bacteria. then you put the mixture, which is now called a recombinant DNA into the bacteria and incubate it so it can grow.
What are the transgenic bacteria?
Trangenic bacteria are bacterial colonies which are genetically modified by deleting or adding a particular gene sequence.
