The answer is that both blunt ends and sticky ends can be created when restriction enzymes cut DNA.
To understand why, let's first explain what restriction enzymes are. Restriction enzymes are proteins that can recognize specific DNA sequences called recognition sites. When a restriction enzyme finds its specific recognition site, it will bind to the DNA strand and cut it.
Now, there are two types of cuts that restriction enzymes can make.
1. Blunt ends: When a restriction enzyme cuts straight through the DNA strand at its recognition site, it creates blunt ends. These ends are called blunt because they have no overhanging or sticky sequences.
2. Sticky ends: In some cases, restriction enzymes can create cuts that are not straight through the DNA strand but rather staggered. This results in sticky ends. Sticky ends have short overhanging sequences of single-stranded DNA, which can base-pair with complementary sequences on other DNA fragments.
So, depending on the specific restriction enzyme and where it cuts the DNA, it can generate either blunt ends or sticky ends.
