This state is characteristic for recessive traits. For an individual to express a recessive trait, it must have two recessive alleles (one of two or more alternative forms of a gene) of the responsible gene. But, if it has one recessive allele and one dominant allele, it will not have the trait, but he will be called a carrier. So, it seems like the trait "disappeared" but still it is "carried" in the genome. However, if its offspring has two recessive alleles and express the trait, it will <span>seem </span>like the trait "reappeared".

Why do the cells transformed with PUC18 and plasmid lux grow in the presence of ampicillin?
Fofino [41]

Answer:

The bacterial cells transformed with PUC18 and plasmid lux grow in the presence of ampicillin, because the DNA of bacterial cells had incorporated parts of plasmid DNA and became ampicillin resistant.

Explanation:

The bacteria showing this property is mainly known as Escherichia coli (E. coli). These bacteria cells generally shows no growth in presence of antibiotic like ampicillin. Whereas when these cells are treated with PUC 18 and plasmid lux, then the bacterial DNA undergo certain transformation due to incorporation of strands of DNA of plasmid into them. This transformation make them resistance to ampicillin, when they are cultured in agar media with ampicillin in it.
