The restriction enzyme bamhi recognizes the dna sequence ggatcc and always cuts between the two g nucleotides. how many bases long is the sticky end of a dna molecule that has been cut with bamhi?

The correct answer is four base pairs.

BamHI is endonuclease meaning that it has the ability to cut DNA at specific target site. The recognition sequence of BamHI is 5'-GGATCC-3 and it cleaves it after the first G. Sticky ends are formed as a result of that cleavage remaining a four-base 5' overhang in one molecule and a complementary 5' overhang in the other. These ends are can be joined back together by an enzyme called ligase.

explanation:

amber has allowed scientists to study dna that has been preserved over millions of years.
