Answer:

In gel electrophoresis, the marker DNA helps in calculating the size of any DNA band on the same gel, and also in other lanes. Following electrophoresis, the gel band of a marker DNA such as the Lambda is likely to display an extra band as a result of the connection of the both end fragments.

In gel electrophoresis, the marker DNA (eg. lambda cut withHindIII)

is useful for sizing of linear double-stranded large DNA fragments and to

show area of migration.

Gel electrophoresis helps to separate mixtures of DNA, RNA, proteins etc to

different parts according to their molecular size. It requires an electric field

pushing the molecules through a gel.

The marker DNA (eg. lambda cut withHindIII) is used when there is

digestion with a restriction enzyme (such as HindIII). This helps to determine where DNA fragments of particular lengths will migrate.
