Answer:
Option
Explanation:
Beta-galactosidase is a protein encoded by the lacZ gene and the process of alpha complementation is used in identifying the vector recombinant,
The insertion of the target DNA fragment into a vector; whose inactive beta galctosidase has been made functional by adding an alpha peptide will disrupt the complementation process and then render the protein non-functional such that the transformed bacteria cells becomes sensitive to antibiotic treatment and then proceed to form white colonies in the presence of X-gal. While cells that have plasmids with DNA inserts will remain resistant and form blue colonies in the presence of X-gal.
Answer:
Cells typically communicate using chemical signals.
