The DNA migrated to the positive pole of the electrophoresis chamber because the DNA's chemical structure is negative.

As we know, opposite attracts. Negative is attracted to positive, that is why the DNA migrated to the positive pole of the electrophoresis chamber.

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.

Katarina [22]

Answer:

The Pepsi he drinks at 10 pm

Explanation:

Pepsi is a caffeinated drink that has caffeine in it. Caffeine is a stimulant which means it keeps the body awake and alert. Caffeine works by mimicking adenosine. Adenosine is produced by neuron cells and when it binds to its own receptors (autocrine signaling) it triggers the neurons cells to continue firing. As the adenosine levels fall as the day progresses, the brain is signaled that it is time rest. Adenosine levels are at the lowest when its almost bedtime. However, when Jon takes Pepsi, the caffeine in it bind to the adenosine receptors and make the brain neurons to keep ‘firing’.
