Restriction enzymes are used in making recombinant dna. describe the role restriction enzymes perform when constructing recombinant dna. (60 points to the person who answers)

Restriction enzymes identifies specific sequences in the DNA (Deoxyribonucleic acid) and cut the DNA to produce fragments. These enzymes are used in the production of the recombinant DNA. These enzymes cut out the specific required fragment of the DNA, which is then incorporated into the bacteriophage. This recombinant phage DNA then infects the bacterial cell, which produces new particles with this foreign recombinant DNA.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
