If a mutation removes a restriction site what can happen to the fragment pattern?
A. एक cut कम हो सकता हैOne cut may be lost
Restriction site हटने पर expected cut नहीं होगा। इससे larger fragment दिख सकता है। / When a restriction site is removed the expected cut will not occur. This may show a larger fragment.
