Answer:
Restriction enzymes (endonucleases) are used to cut the DNA into fragements.
Explanation
Restriction enzymes are obatained from bacteria where they are utilized by bacteria for protection against viruses. Restriction enzymes are used in biotechnology research. There are several restriction enzymes and each cut the DNA at specific site known as recognition site which is usually 4-8 neucleotide long. They produce sticky ends (cutting the both DNA strand on different site) and blunt ends (cutting the both DNA strand on same site) on DNA fragments.
I hope this help but the metalloids is gruop five if that what your asking if not i will answer the other question for you

The correct answer is C.
(The nonspecific response provides an immediate response, while the specific response involves a delay between exposure and response.)
- The non-specific immune response is the first line of protection from different types of pathogens and microbes such as skin (physical barrier). It is immediate response however, it is not specifics and it does not involve the recognition of pathogens.
- The specific immune response depends on pathogen recognition and therefore is long-lasting immunity and it takes time to be effective. This response includes B- cells, T-cells, phagocytic cells and NK cells.
