When dna microarrays containing asos are used to genotype snps, what form of dna constitutes the probe molecules?
umka2103 [35]

DNA microarray uses 20-40 sequence-specific oligonucleotides as probes to identify the SNP.

DNA microarray is a technique used to measure gene expression. It works on the principle of hybridization.

The genome of the reference organism is attached to a solid surface (silicon chip). The DNA of the test organism is made to hydride with the reference organism. Depending on the level of hybridization the fluorescent or the chemiluminescent is measured to identify the expression.

Single nucleotide polymorphism (SNP) is the change in the single nucleotide of the genome. SNPs can be identified with the help of DNA microarray.

Elena L [17]

</span>

<span>Phosphorus is not abundant in the atmosphere. It comes mostly from the land and ocean. Phosphorus cycle through the lithosphere, hydrosphere, and biosphere, but not the atmosphere. The reason for this is that phosphorus cannot be found in the gas state, unlike the sulfur. On the other hand, sulfur cycle partially occurs in the atmosphere.</span>

Which term specifically describes the categorization of people into ethnic groups without taking into account individual differe
zysi [14]

Answer: D) Stereotyping

Choice A is false because this involves denying a person to do something based on factors such as religion, race, ethnicity, etc.

Choice B is false because this term involves a crime or suspected crime being committed, or about to be committed. And it also makes the assumption based on a person's race.

Choice C is false since segregation is the separation of people usually by race or ethnicity. Though you could have class based segregation (eg: rich vs poor) and other forms.

Choice D is true because stereotyping is where you lump a bunch of people together based on cultural or societal assumptions. Usually it's in the form of "all ___ people do such and such" where you fill in the blank with a specific race or culture.
