Suppose you cut dna you know that you should find four dna fragments on a gel, but only three appear and one fragment is very large. Explain what happen

Restriction Mapping

Explanation:

A mutation has occurred and can be known that how many need to be seen by looking at a similar sequences restriction map, indicator of genetic disease  

Restriction mapping is the technique which is used to determine the relative location of restriction sites on a DNA fragment to give a restriction mapRestriction enzymes recognize specific sequences on DNA and make specific cuts Restriction mapping involves the positioning of relative location of restriction sites on a DNA fragmentSome enzymes require four bases as a restriction sites and make frequent cuts and generate small fragments while some enzymes recognize six bases or eight bases and make rare cuts to generate large fragments DNA fragments after the digestion are separated in agarose gel In the given question one fragment comes out to be very large,it is possible that mutation might have occurred and which can be observed by looking at other restriction map of similar sequences

idk but if i had to take an educated guess i’d say a c d
