What else can I help you with?
In the control of gene expression in bacteria a regulatory gene a has its own promoter?
The regulatory gene a has its own promoter to enable transcription of the gene. This promoter allows for the synthesis of the regulatory protein encoded by gene a, which can then regulate the expression of target genes in response to specific signals or conditions in the bacterial cell. By controlling the production of this regulatory protein, bacteria can fine-tune their gene expression patterns for adaptation and survival.
During telophase, what process occurs that allows chromosomes to uncoil and facilitate gene expression?
During telophase, the process of chromatin condensation occurs, which allows chromosomes to uncoil and facilitate gene expression.
Bacteria containing a plasmid into which the eukaryotic gene has integrated would grow where?
The bacteria containing the plasmid with the integrated eukaryotic gene would grow in a selective medium that supports the growth of bacteria carrying the plasmid. This medium would typically contain an antibiotic or a specific nutrient that selects for bacteria with the plasmid.
What is the direction of transcription in the process of gene expression?
During gene expression, transcription occurs in the direction from the 5' to the 3' end of the DNA strand.
What is transcription and translation in gene cloning?
Transcription is the process of transcribing DNA into RNA, which occurs in the nucleus of a cell. Translation is the process of converting the RNA sequence into a protein, which occurs in the cytoplasm of a cell. In gene cloning, these processes are used to generate copies of a specific gene of interest, which can then be inserted into a host organism.
What gene makes it possible to identify bacteria that carry a plasmid?
The gene commonly used to identify bacteria carrying a plasmid is the beta-lactamase gene, which confers resistance to beta-lactam antibiotics. Bacteria harboring plasmids with this gene can be identified by growing them on agar plates containing beta-lactam antibiotics and observing which colonies survive.
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.
Which molecule from humans is inserted into bacteria to cause them to produce insulin?
The human gene that codes for insulin is inserted into bacteria to produce insulin. The gene is typically inserted into a plasmid vector, which allows the bacteria to express the human insulin gene and produce insulin. This technique is used in biotechnology to create recombinant bacteria that can produce insulin for medical use.
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 is transformation in DNA?
transformation is the process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria
Why does the capability of bacteria to replicate itself rapidly a useful tool for gene cloning?
Make lots of copies of the gene rapidly.
In the control of gene expression in bacteria a regulatory gene a has its own promoter?
The regulatory gene a has its own promoter to enable transcription of the gene. This promoter allows for the synthesis of the regulatory protein encoded by gene a, which can then regulate the expression of target genes in response to specific signals or conditions in the bacterial cell. By controlling the production of this regulatory protein, bacteria can fine-tune their gene expression patterns for adaptation and survival.
What is the ampr gene?
The ampr gene encodes for the enzyme beta-lactamase, which confers resistance to ampicillin in bacteria. This gene is often used as a selectable marker in molecular biology experiments to identify transformed cells that have taken up a plasmid with the gene.
Why is a white tiger white?
It's due to a recessive gene in the tiger gene pool that only comes about when inbreeding occurs, which rarely, if ever, occurs on the wild; only in captivity is this able to occur.
During telophase, what process occurs that allows chromosomes to uncoil and facilitate gene expression?
During telophase, the process of chromatin condensation occurs, which allows chromosomes to uncoil and facilitate gene expression.
Why does a probe hybridize to a target gene but not to any other unrelated gene?
Complementary base pairing occurs only between the probe and the target gene.
