Question

18. Shown below are the results of a series of coinfections of E. coli B using T4 rll- strains similar to those employed by B19. In a haploid yeast strain, six different mutants unable to grow in the absence of glutamine were isolated. Mutants #1 andAnswers are C,A. Please explain the method to fix this kind of questions. Thanks

Answer #1

Ans:

18: Deletion E overlaps deletions B and C, which don't overlap each other. Therefore E is between B and C.

so, (c) ABECD

    5. Deletions can be used to map genes along a chromosome. In order to do this a series of crosses in which one parent is homozygous for a mutant allele is crossed with the other parent that is homozygous for a partial deletion of the region. The progeny are scored to determine whether they have the mutant phenotype ("m") or the wild-type phenotype ("+"). If the mutant allele falls within the deletion it will have the "m" phenotype, if it...

Seven non-reverting mutations at the nii locus of T4 were used to co-infect E.coli strain B at high multiplicity of infection. The lysates from each co-infection were then in spotted onto a lawn of strain K to test whether they could infect and lyse strain K. The results of this test are shown in the following table, where "+" indicates lysis of strain...
