Answer 1

Answer:

DNA molecule in gel electrophoresis is seperated on the basis of size

the smaller fragment move more away from well

Answer 2

Answer:

In agrose gel electrophoresis, DNA molecules are seprated on the basis of Size .

Explanation:

● In gel electrophoresis, agrose gel is used to separate DNA fragments on the basis of their size. Agrose gel is used because they have bigger pores and easily seprate dna molecules of different size.

● DNA molecules migrate in a gel electrophoresis according to the size. Agrose gel concentration is also an important factor which determine the rate of migration.

● Other factor also, like presence of Ethidium bromide, type of agrose gel and what percentage of agrose gel is used and amount of electrophoresis buffer present, all these factors affect the migration of DNA molecules.
