Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.
Out of the choices given, the mechanisms that drives evolution is natural selection. The correct answer is B, natural selection.
Asynchronous Learning is when each student works at their own pace, and may not collaborate on work in class meetings, so the correct answer here would be D!
The answer is a low-density particle
Thymine, Guamine, cytosine, and atanine make up the steps in dna (the nitrogenous bases) but the sided are a patter of phosphate then sugar.
- hope this is what you were wanting
