In the body, bacteria reproduce at a rapid rate. Some bacteria populations that are harmful to humans are evolving today so that they are becoming resistant to all medicines used to fight them.Scientists are studying how CRISPR-Cas9 can be used to solve the growing problem of antibiotic resistance. The idea is to use a virus to insert guide RNA into a bacterium. That guide RNA instructs the bacterium’s own immune system (the CRISPR-Cas9 system) to cut out its own DNA. The immune system then turns against the bacterium, killing it. Which question below do scientists need to answer, to determine whether CRISPR can be used to fight a new bacterium that is resistant to antibiotics? (Select all that apply) What sequence of nucleotides does the guide RNA need to include, to kill the bacterium? Where did the bacterium come from? What proteins do the virus’s guide RNA code for?

As we know CRISPR are repetitive sequences in bacterial DNA, that work as a "self vaccine" that is to say contain the genetic material of the viruses that have attacked them, this way they recognize the alien element and cut their DNA. Taking this into consideration we can say that the correct answer is, What sequence of nucleotides does the guide RNA need to include, to kill the bacterium? as is necessary a guide where to start the process, a primer.
