Suppose you infect E. coli cells with two strains of T4 virus. One strain is minute (m), rapid lysis (r) and turbid (t); the other is wild-type for all three markers. The lytic products of this dual infection are plated on a lawn of E. coli and the morphology of […]

In mice the allele for colour expression is C (c= albino).Another gene determines colour (B= black, b= brown). Yet another gene modifies the amount of colour sothat D= normal amount of colour and d= dilute (milky) colour. Two mice that are CcBbDd aremated. a. What proportion will be dilute brown?b. […]

Question: In yeast, one haploid strain is unable to synthesize uracil but able to synthesize leucine, while another haploid strain is able to synthesize uracil but not leucine. You think that the two genes occurring on different chromosomes permit synthesis of uracil and leucine. Your goal is todetermine if the two genes occur […]

Q1. Animals can be genetically modified as well. What components of PCRs require to be changed in order to identify genetically modified meats or milk? Generally give details why those changes need to be made. Q2. There are a variety of media; each one identifies different properties of the organism […]
