Human insulin can be produced by bacteria when the human gene for insulin is inserted into the bacterial plasmid. what is used to cut the gene from the human dna?

a. scissors
b. restriction enzymes
c. dna splicers

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.
