Friedel-Crafts catalysts

Restriction enzymes

Grignard reagents

Diels-Alder reagents

Verified step by step guidance

Identify the purpose of each molecular tool listed in the options. Friedel-Crafts catalysts are used in electrophilic aromatic substitution reactions, Grignard reagents are used to form carbon-carbon bonds, and Diels-Alder reagents are used in cycloaddition reactions.

Understand the role of restriction enzymes in molecular biology. Restriction enzymes are proteins that cut DNA at specific sequences, which is crucial for assembling recombinant DNA.

Recognize that the question is asking for a tool used specifically in the context of assembling recombinant DNA, which is a process involving the manipulation of DNA sequences.

Eliminate the options that do not relate to DNA manipulation. Friedel-Crafts catalysts, Grignard reagents, and Diels-Alder reagents are not involved in DNA assembly.

Conclude that restriction enzymes are the correct choice as they are specifically used to cut and assemble DNA fragments, making them essential for recombinant DNA technology.
