I like to make flash cards and have someone else help with answering. Write a question on one side and the answer on the other, and you can even do it yourself.
Answer:
This BclI restriction enzyme recognizes and cut at T / CTAG nucleotide sequences.
Explanation:
5′ CCGCGGT 3′
3′ GGCGCCACTAG 5′
Segment 2
5′ GATCAGGATCC 3′
3′ TCCTAGG 5′
The BclI enzyme generates sticky ends, it means that the enzyme recognises and cuts nucleotide sequences without complementary bases, which also have weak hydrogen bonds. The sticky ends are then generated when an enzyme produces unpaired nucleotide ends. Nonetheless, restriction enzymes generally produce blunt ends, i.e., both strands cut at the same site.
