The figure provided portrays the integration of Lambda phage into a host chromosome at the att site, located between the gal+ and bio+ genes. This prophage may disintegrate from the host carrying with it host genes, such as gal+ and/or bio+ and go on to transduce another host bacterium. How would one determine if a gal- host bacterium's phenotype was changed from gal- to gal+? To clarify, the minus version cannot utilize galactose as a carbon source for growth because it does not produce galactase, the enzyme that hydrolyzes galactose into monomeric sugars. There is a straight forward answer/solution to this – do not concoct some crazy solution! Think simple experiment.

The attack of a host cell is necessary for the virus to survive for all of the reasons listed EXCEPT one. That is they cannot synthesize proteins becayse they lack ribosomes and must use the ribosomes of their host cells to translate viral messenger RNA into new Eliminate proteins. A) they cannot produce or store energy in the form of ATP and have to get their energy from the host cell. B) they parasitize the host cell for basic molecules like amino acids, nucleotides, and lipids. D) they lack DNA/RNA so they must use the DNA of the host cell. Address 立
