Is this cell in a hypotonic or hypertonic solution? 

Match the blanks with the appropriate word (5 pts): In recombinant DNA technology, [A] are used to cut a specific gene out of a piece of DNA. The gene may be inserted into a [B], which carries a gene for streptomycin resistance, and serves as a gene vector. The gene vector is put into a bacterial cell using [C]. Only bacteria that take up the gene vector will grow in the presence of [D]. The bacteria grow and multiply, producing the [E] coded for by the gene vector.
