Do dominant alleles move farther in electrophoresis?
Not always. Different chromosomal fragments travel different distances in electrophoresis due to their different lengths. Longer fragments are heavier and therefore travel shorter distances under the same electrical force.
What does the charge of DNA have to do with DNA fingerprinting?
DNA is of a negative charge. So when gel electrophoresis is used on it the DNA fragments are attracted to the positive end of the electrophoresis. The fragments of different lengths travel down the gel towards this end. The longer length fragments travel less and so are farther from the positive end. By looking at these DNA fragments, which are created by cutting DNA with restriction enzymes one can compare and contrast DNA. Thus DNA fingerprinting can take place based on the different restriction sites in DNA (cut by the enzymes) forming different length segments of DNA.
How does a year on earth differ with other planets?
A year on Earth is longer than it is on two other planets, and shorter than it is on the remaining five. The farther a planet is from the sun, the longer its year is.
Is mars day longer or shorter or longer than earths?
longer
Why do different planets have different length orbits?
Different planets have different orbit lengths because of their distance from the sun. Planets closer to the sun have shorter orbits, and planets farther away have longer orbits.

What determines the distance of the DNA fragments?
By the size of the DNA molecule. longer DNA molecules move slower, and shorter DNA molecules move faster!
What is the effect of the run time on the observed pattern of restriction fragments?
the longer the run time the better the results?

Does lenght of leg affect running speed?
The longer your legs are, the longer your stride is and the farther you'll be able to go in the same amount of time it takes a shorter person.
Six inches are shorter than four inches?
No, that's not true. An inch is a length or distance. Six of them are longer/farther than four of them.
Explain how an agarose gel can separate DNA fragments of different lengths.?
The separation of DNA fragments is based on size. When a DNA sample is run in a gel (electrophoresis), the lighter fragments migrate faster than the heavier (longer) fragments under the influence of an electric current. At the and of the process, the shorter fragments are found at the terminal end of the gel and the longer fragments closer to the origin
How does a year on earth differ with other planets?
A year on Earth is longer than it is on two other planets, and shorter than it is on the remaining five. The farther a planet is from the sun, the longer its year is.
How does the season affect the length of the day?
Depending on the distance from the equator, you get longer days in summer and shorter in winter. The farther from the equator the more pronounced the difference becomes.
Why do the waves with shorter wavelengths scatter more than those with long wavelength?
Because they use less energy then longer wavelengths hence they can go farther
During gel electrophoresis do long or short fragments travel more quickly toward the positive pole?
Short fragments are able to move faster (longer = heavier = slower).
Why is the longer leg longer than the shorter leg if the shorter leg is longer than the longer leg?
Because if the shorter leg was shorter than the longer leg was long, then the longer leg wouldn't be longer than the shorter leg is short. The short leg would be the longer one rather than the long one being the short one.
