How can a proto oncogene be converted into an oncogene without a change or mutation in its coding sequence?
It could happen in three main manners: 1) the formation of multiple copies of the gene (duplications) that increase the expression of the gene 2) the mutation happens in the promoter of the gene or in others non coding regions causing an increase in the level of the mRNA of the gene 3) it could happen a translocation that put the gene under an active promoter (bcl2 in lymphomas) , or brings to the formation of a chimaeric gene (the philadelphia chromosome in leukemia)

What kind of mutation is tag ctt ggc at?
The sequence "tag ctt ggc" provided does not represent a specific mutation. A mutation would involve a change in a specific base or bases within a DNA sequence. Without further context or details, it is not possible to determine the type of mutation.
What this the relationship between DNA mutation and cancer?

What is isogenic mutation?
Isogenic mutation refers to a genetic mutation that occurs in an organism's DNA, resulting in a change in a specific gene or genes. It is called isogenic because it affects only a specific gene in an otherwise identical genetic background. This type of mutation is often used in research to study the effects of a single gene mutation without any additional genetic variability.
Does the prion protein contain a signal sequence?
Yes, the prion protein does not contain a signal sequence. It is primarily localized to the cell membrane without the need for a signal sequence to direct its insertion.
How can a mutation that alters a recognition site be detected by gel electrophoresis?
First, DNA that is mutated and unmutated must be cut with the same restriction enzyme. When these two strains of DNA are run through gel electrophoresis side by side, the mutated DNA will have fewer bands and at least one that does not move as far as the normal DNA. This is because the the restriction enzyme would not cut at the mutated recognition site. The difference in bands in the agarose gel will easily be detected.

What One example of a mutation that would not affect an organisms phenotype?
A silent mutation is an example of a mutation that would not affect an organism's phenotype. This type of mutation occurs in a non-coding region of DNA, such as an intron, and does not change the amino acid sequence of the protein produced. Therefore, it has no impact on the organism's outward appearance or characteristics.
Why is mutation important to spectation?
Without mutation there can be no evolution. Without evolution there can be no speciation.
Why it is important for a cell to copy DNA without making mistake?
It is important for cell to copy DNA without making mistake because the DNA contain genetic code in the form of nucleotide base pair sequence, if those sequence get wrong then the DNA code for wrong gene i.e. there will be a mutation which can be lethal or dangerous.
What is a harmful mutation?
a mutation is sometimes a form of adaptation, but if something changes in the DNA of the species and could possibly be harmful to it, that is a harmful mutation.Examples:-born without a part of the brain-cancer is a form of a harmful mutation-hypoglycemia

What is regulatory mutation?
A regulatory mutation is one that occurs in the promoter or operator region of a gene or set of genes and affects the expression of the downstream genes without affecting the amino acid sequences of the gene products.

What is the next letter in sequence a e a p a?
The sequence provided is not following a clear pattern based on typical alphabetical order or common sequences. Without a clear pattern to follow, it is difficult to determine the next letter in the sequence. It appears to be a random sequence of letters without a discernible rule or logic.
