A person has the genotype of 9, 9 on one of his microsatellite loci. An electrophoresis was conducted on the PCR products of this locus. Which lane on the gel below is most likely the result of the PCR fragments

A person has the genotype of 9, 9 on one of his microsatellite loci.

An electrophoresis was conducted on the PCR products of this locus. Which lane on the gel below is most likely the result of the PCR fragments

Lane: A

Explanation:

DNA´s negative charge, given by phosphate groups is carried applying electrophoresis, on an agarose gel matrix, so that the equally-sized fragments put up at the same spot on the gel. After applying power, DNA fragments migrate to the positive electrode due to the enforced power, that way smaller fragments travelling faster, and larger fragments travellying slow, are size-sorted

We can see the gotten diagram for this person:

Column A as the most likely PCR fragments.

L= size ladder

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
