Here are some examples:
* SmaI: This restriction enzyme recognizes the sequence CCCGGG and cuts directly in the middle, creating blunt ends.
* EcoRV: This enzyme recognizes the sequence GATATC and also cuts directly in the middle, producing blunt ends.
* AluI: This enzyme recognizes the sequence AGCT and cuts between the G and C, creating blunt ends.
In contrast, enzymes that create sticky ends cut DNA asymmetrically, leaving overhangs of single-stranded DNA. These overhangs can then base-pair with complementary overhangs on other DNA fragments, allowing for the joining of different DNA molecules.
Examples of enzymes that create sticky ends include:
* EcoRI: This enzyme recognizes the sequence GAATTC and cuts between the G and A, leaving a 5' overhang.
* HindIII: This enzyme recognizes the sequence AAGCTT and cuts between the A and A, leaving a 5' overhang.
* BamHI: This enzyme recognizes the sequence GGATCC and cuts between the G and G, leaving a 5' overhang.
