What is Heterozygote detection?
Why was rii locus chosen by Benzer for his experiment?
A blastomere was removed from an 8-cell human embryo, and its beta-globin gene was amplified by PCR. The beta-globin DNA was treated with an enzyme that cuts on either side of and within the normal allele (producing a small fragment), but not within the sickle cell allele (producing a large fragment). Electrophoresis of the treated DNA from the blastomere demonstrated the presence of both a large and small fragment derived from the beta-globin genes. How should you interpret this test?
How is Genetic Engineering currently used?
In the definition of mutation we say sudden heritable change i the DNA, so what does sudden means here?
A base deletion occurs in the regulator gene of the LAC operon. Describe how the operation of the LAC operon might be affected?
Promoters of housekeeping genes contain variable numbers of GC boxes, but neither TATA nor CCAAT boxes.Inwhat way these properties of housekeeping promoters are helpful?
how to Create population with sufficient genetic diversity ?
Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
How will you differentiate alleles of a gene in the double strand of DNA?
A single base exchange mutation occurs in the promoter of the TRP operon. How the operation of the HIS operon might be affected in two ways?
Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
In mice colored coat is dominant to albinism. Sniffles, a male mouse with a colored coat is mated to Esmeralda, an alluring albino. The resulting litter of six young all had colored fur. The next time around Esmeralda was mated with Whiskers, who was the same color as Sniffles; some of this litter were white. a)What are the probable genotypes of Sniffles, Esmeralda, and Whiskers? b) If a male of the 1st litterwas mated to a colored female of the 2nd litter, what phenotypic ratio might be expected among the offspring? c)What would be the expected results if a male of the 1st litter was mated to an albino from the 2nd?
