at which level of gel , the sample was loaded in gel electrophoresis ?? label in the colours of bands of dna in lithium bromide stained gel..DONT SPAM PLZZ ITS MY REQUEST
Answers
it is a technique used to separate dna fragments
Answer:
DNA fragments are divided using the gel electrophoresis technique based on their size.
An electric current is used to draw DNA samples across a gel after they have been inserted into wells (indentations) at one end of the gel.
Due to their negative charge, DNA fragments gravitate toward the positive electrode. Smaller DNA fragments move through the gel more quickly than larger ones because they all have the same amount of charge per mass.
DNA fragments appear as bands on a gel after being dyed with a DNA-binding dye; each band represents a collection of identical-sized DNA fragments.
The gel has wells at one end that resemble pockets; these wells will hold the DNA samples.
