Ascientist wants to insert a new gene into a bacterium. what is the first step in this process? a) bonding the gene into a plasmid with enzymes. b) placing the changed plasmid into bacteria. c) inserting the gene into a plasmid. d) cutting the gene out of dna with enzymes.

Option D, cutting the gene out of DNA with enzymes

Explanation:

The  first step in inserting a new gene into a bacterium is the separation of gene (to be inserted) from the parent cell DNA

Restriction enzyme (RE) is a DNA cutting enzyme which is used to cut this DNA. RE identifies a specific target sequence with in a DNA and then cut the DNA into two pieces either at or near the site.
