The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Restriction Enzymes**: Restriction enzymes are proteins that can cut DNA at specific sequences. They recognize particular sequences of nucleotides, which are often palindromic. 2. **Discovery of Sticky Ends**: The ability of restriction enzymes to cut DNA in a way that leaves overhanging ends, known as "sticky ends," was discovered by Herbert Boyer. Sticky ends are created when the enzyme cuts the DNA in such a way that one strand extends beyond the other. 3. **Mechanism of Action**: When a restriction enzyme cuts the DNA, it does so at specific sites, which leads to the formation of these sticky ends. The sticky ends are essential for the ligation process, where DNA fragments can be joined together by complementary base pairing. 4. **Role of Other Scientists**: While Herbert Boyer is credited with the discovery of sticky ends, other notable scientists mentioned include Stanley Cohen, who worked alongside Boyer, and James D. Watson, who is known for his work on the structure of DNA. Ramdev Mishra is recognized for his contributions to ecology, not molecular biology. 5. **Conclusion**: The correct answer to the question of who discovered the capability of restriction enzymes to create sticky ends is Herbert Boyer.

A plasmid has two antibiotic-resistance genes, one for ampicillin and one for tetracycline. It is treated with a restriction enzyme that cuts in the middle of the ampicillin gene. DNA fragments containing a haemoglobin gene were cut with the same enzyme. The plasmids and fragments are mixed, treated with ligase and used to transform bacterial cells. Clones that have taken up the recombinant DNA are the one that
