Answer: <u>Guanine
</u>
According to Chargaff's rule, the base pairing in the DNA and RNA is fixed. Adenine always pairs with Thymine in DNA and Uracil in RNA. Guanine pairs up with cytosine. This complementary base pairing is universal and constant. That's why amounts are also equal. It means if cytosine is 20% in any DNA sample, then amount of guanine would be 20% as well.

Eukaryotic cells have a nucleus and prokaryotic cells do not.
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.
