The scheme of modern taxonomy goes:
Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species
So, a PHYLUM is made of several classes.
How are DNA fragments separated using gel electrophoresis? ... A solution ofDNA molecules is placed in a gel. Because each DNA molecule is negatively charged, it can be pulled through the gel by an electric field. Small DNAmolecules move more quickly through the gel than larger DNAmolecules.Nov 20, 2007
Answer:
C. This is an example of VNTRs.
Explanation:
VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.
DNA is the correct answer but next time put answer choices so that people can better answer your questions. Thanks!
I think it’s B, sorry if I’m wrong
