Glacier is any large mass of ice that slowly moves over land. <span>Glaciers erode the land through two processes called plucking and abrasion.</span><span>
The process by which a</span>s a glacier flows over the land, it picks up rocks in this process is called plucking.
A DNA molecule with 1000 base pairs would further in the gel more than one with 200 base pairs.
The speed at which the molecules move through the pores in the gel is inversely proportional to their lengths. This indicates that a smaller DNA molecule will move through the gel further than a larger DNA molecule.
Gel electrophoresis is a method that researchers use to measure the size of DNA fragments. In this procedure, tiny holes called wells are positioned at the edge of a gel along with unknown samples and a DNA standard. The standard includes base pair-measuring fragments of known sizes.
DNA has 200 bases, so 2003420=340A.
A DNA segment that is 1700 base pairs long therefore contains 500 base pairs or 1000 nucleotides.
