What happens when there are changes in a gene?
The protein that the gene codes for changes or may even cease to be produced, depending on the change to the gene.
What are three main types of gene mutations what happens in each gene?
They are Substitution, Insertion, and Deletion.
What happens when a steroid hormonoe binds to a receptor?
acts as a transcription factor and binds to DNA, activating a gene
If a specific kind of protein is not continually used by a cell the gene for that protein is?
the gene is never expressed. ^^^^ this guy is a frickin idiot. and this would more of be in the cells/ biology section. What happens is a repressor binds to the operator and turns off the gene so the protein doesn't get made. and when its needed the repressor detaches and the gene is turned back on. ( this all happens on a strand of DNA )
What is gene sequencing used to determine?
When you hear gene sequencing you first think of DNA mapping. We think of paternity tests but gene sequencing has been used to determine diseases. More recently it has been used to directly help the patient with proper diagnoses.
Gene feels a certain amount of towards Finny?
Gene feels jealousy towards Finny because he admires his athletic abilities and popularity, which Gene lacks. This jealousy leads Gene to sabotage Finny, ultimately causing a rift in their friendship.
What happens when there are changes in a gene?
The protein that the gene codes for changes or may even cease to be produced, depending on the change to the gene.
How has melanoma been treated with gene therapy?
involves introducing a gene with an anticancer protein called tumor necrosis factor (TNF) into test tube samples of the patient's own cancer cells, which are then reintroduced into the patient.
What is null allele?
A null allele is a mutant copy of gene that completely lacks that gene's normal function. This can be the result of the complete absence of the gene product (protein, RNA) at the molecular level, or the expression of a non-functional gene product. At the Phenotypic level, a null allele is indistinguishable from a deletion of the entire locus.
What are three main types of gene mutations what happens in each gene?
They are Substitution, Insertion, and Deletion.
What happens to the expression of the lacl gene if lactose is not available in the cell?
there is no change--the lacl gene is constitutively expressed
What happens to a gene for a protein that is not used much in the cell?
Nothing "happens" to it. When a gene is not actively being copied or expressed it is folded up and stored till it is needed again.
Who is benefiting from gene therapy?
Gene therapy is technique to treat a genetic disorder or cancer by inserting a gene to replace the defective one.It is now not widely in practice but this may be the future. The benefit is the patient can successfully attain the healthy gene and can be cured permanently.
How gene therapy is used to treat genetic disorders?
Gene therapy is a method that aims to cure inherited diseases by providing the patient with correct copy of the defective gene. There are four potential approaches to gene therapy:1)Addition of normal gene to replace the function of defective gene. This is gene replacement orgene augmentation therapy.2)Replacing the defective gene with the correct gene. This isCorrective gene therapy.3)Establishment of alternative pathways that bypass mutant genes function4)Change in regulation of normal or mutant genesThe first two are the basic approaches in gene therapy
What happens when a steroid hormonoe binds to a receptor?
acts as a transcription factor and binds to DNA, activating a gene
What happens to any population when its small and isolated from gene flow?
Mutations
What happens to Gene and Quackenbush as they are fighting?
Falling into the water
