The answer is length.
A gel electrophoresis is used for separation of DNA or its fragments on the basis of differences in their length. An electric current is running through the gel with positive pole on the bottom. Because of the difference in the lengths of DNA fragments, some <span>of them </span>will travel more quickly than other. It is expected to see smaller DNA fragments at the bottom of the gel and larger DNA fragments near to the top of the gel.
Answer: Mass flow or bulk flow is the movment of substance in big masses or something moving in a big group.
Explanation:
Its kind of like a river or blood flowing through your veins because its a mass of a substance moving in a group.
The smallest dna fragments are located near the bottom of the gel. (Positive electrode)
The largest dna fragments are located near the top of the gel. (Negative electrode, where they began)
Answer: covering crops
Explanation:
such as vetch, rye and clover, are excellent plants for erosion control. These hardy easy to grow plants send out nets of roots that help hold topsoil in place while also reducing competitive weeds. When tilled back into the soil, they increase the nutrient density as they compost.
Answer:
0%
Explanation:
Normal female genotype = 
Genotype of a man with hemophilia = 
Crossing the two in marriage:
x
Progeny: 
<em>The two sons from the cross have the genotype </em>
<em> and are therefore free from hemophilia.</em>
Hence, the percentage of their sons that will have hemophilia is zero (0).
