What types of enzymes are typically constitutively expressed? - enzymes in constant demand In an experiment exploring the expression of DNA repair enzymes, phage exposed to UV light had low infectivity, but when both phage and host cell E. coli were exposed to UV light, normal levels of infectivity resulted. From these data we can infer - host cell genes were used to repair phage DNA The lacZ gene was used in an experiment testing for the expression of gene X. About half the resultin...

Immunity - involves a specific defensive response when a host is invaded by foreign organisms the immune system recognizes foreign substances as not belonging to the body and responds. Antigen - is a substance that provokes an immune response. Immune response - may generate specialized lymphocytes or antibodies specific for the antigen. Acquired immunity - is the protection an organism develops during its lifetime. Active immunity - involves an immune response within the individual. P...
