In Microbiology, we usually identify mutated bacteria/mutants/mutated DNA by using a number of methods, such as:
1.) Positive selection - For example, we want to identify a mutant bacteria that are resistant to antibiotics, such as say, penicillin, a beta-lactam antibiotic. We plate the bacteria in a medium that contains penicillin, if the bacteria is from a pure culture known to be penicillin-sensitive then we could expect that there will be no growth, if there is growth however, we could say that bacteria is mutated and most likely contains the enzyme beta-lactamase.
2.)Negative selection - This process selects a cell that cannot perform a certain function, we ofen times use the technique of replica plating. For example, we plate a pure culture in a medium with histidine, all of these will form colonies. Next is, we transfer the colonies using a sterile velvet into two or more plates, one contains histidine, the other does not. If a colony that is present in the histidine medium is absent in the other medium, we can assume that bacteria has lost its ability to synthesize it's own histidine.

Mutation that involves a single nucleotide is called?
Point Mutation is the mutation that involves a single or few nucleotide. This type of mutation replaces a single nucleotide to another.
How is familial polyposis diagnosed?
The abnormal portion of the gene that causes FAP in most patients can be detected. A blood test can then be performed which identifies family members who have the same mutation. They will eventually develop the condition.

Is Tourette's syndrome a karyotype or pedigree?
Tourette syndrome (TS) is a disorder which can be caused by genetics or certain environmental factors. There is a certain gene which is said to be involved with the onset of TS, but not everyone diagnosed with the disorder has a genetic mutation. When a genetic mutation is present, it affects the chemical balance in neurons, causing the onset of motor and vocal tics. Hope that answered your question.
A mutation that involves one or a few nucleotides is called a?
Sorry to burst the persons bubble that said frameshift mutation but its wrong. Point mutation-gene mutation involving changes in one or a few nucleotides. point mutation
A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
