Cells may not inactivate a mutant gene due to various reasons, including the lack of effective regulatory mechanisms that recognize and silence the mutation. Additionally, some mutations may not significantly disrupt the gene's function, allowing it to persist. Epigenetic factors and the cellular context can also play a role, as certain mutations may lead to adaptive advantages or be masked by other genetic influences, preventing the cell from recognizing the need for inactivation.

Scientists were studying a mutant gene.


Are mutant genes helpful or harmful?

they can be both if the mutant gene causes the organism to have a new property which improves its life it is helpful and evolution occurs since due to natural selection offspring having the mutant quality will be produced. on the other hand if a mutant gene causes a deformity, or a weakness it is harmful. for example cancer cells, which eventually form a tumour are the result of mutation


What is functional complementation?

Functional complementation is a genetic technique used to identify a gene by introducing a mutant organism with a defective gene to see if another organism with a functional copy of that gene can rescue the mutant phenotype. If the introduced gene can restore the normal function, it indicates that the gene is responsible for the observed phenotype in the mutant organism.


What could cause a mutant fly embryo to develop two tail ends but no head?

This is called bicoid mutant phenotype, and is caused by a maternal effect gene which is a gene that, when mutant in the mother, results in a mutant phenotype of the offspring regardless of the offspring's genotype.

What type of gene is used to distinguish bacteria that carry a plasmid containing foreign DNA from those that don' t?

The plasmid that contains foreign DNA is engineered to also carry an antibiotic resistance gene. This antibiotic resistance gene codes for a protein that is able to inactivate an antibiotic thus keeping the cell alive. In the absence of the antibiotic resistance gene, the cells would not survive when exposed to an antibiotic. After transfection (the process of inserting the plasmid carrying the foreign gene into cells), the cells are gown in media containing an antibiotic. Cells that contain the plasmid (and therefore contain the antibiotic resistance gene) are able to survive in this medium. Cells that do not contain the plasmid (and therefore lack the antibiotic resistance gene) do not survive in this medium. The process described above is called selection

Is there a definition of a mutant in any of the X-Men comic book series?

Yes.When a human is born with the mutant gene you are a mutant. But if you get the abilities later in life(ex.Spiderman) you are mutated.


How storm became mutant?

In the Marvel Universe, mutants like Storm are born with a special gene, referred to as the X-Gene. Usually when a mutant reaches puberty their powers and physical mutants appear.


What are the potential consequences when an individual possesses two different mutant alleles of the same gene?

When an individual possesses two different mutant alleles of the same gene, it can lead to a genetic disorder or disease. This is because the two mutant alleles may not work together properly, causing the gene to function abnormally. This can result in a range of health issues, depending on the specific gene and mutations involved.


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 process involves using primer and Taq in detemining whether a person has a certain mutant gene?

The process used is PCR = Polymerase Chain Reaction. PCR used Taq polymerase - an enzyme that adds nucleotides to a primer and brings about the formation of new double stranded DNA. Primers are short sequences of nucleotides that bind to the mutant gene and allow the Taq polymerase to function. The ultimate result of the process is the amplification (creation of several million copies) of the mutant gene. In the absence of the mutate gene, these copies would not be created since the primers do not have anywhere to bind to.
