1 3952Promoters of housekeeping genes contain variable numbers of GC boxes, but neither TATA nor CCAAT boxes.Inwhat way these properties of housekeeping promoters are helpful?
2156Suppose you are heterozygous for a mutant beta-thalassemia allele. If the frequency of beta-thalassemia is 1/1600 persons, what is the probabilty that your prospective spouse is heterozygous for a mutant beta-thalassemia allele?
2147The village of Oblong has 400 normally-shaped residents. Transferrin is an iron carrier found in blood, and electrophoretic variation of this protein is determined by an autosomal codominant system. The citizens of Oblong were typed for their transferrin complements. The distribution of transferrin phenotypes was: 100 CC, 100 CD, and 200 DD. What is the frequency of the C allele?
1 3030Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child?
2307A 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?

I am an B.Tech Industrial biotechnology fresher(2010 passed out). I am looking for job in biotech companies. I approached some companies too. But in all companies they said they need experienced persons only and not freshers. Please suggest me a solution to my job search. And suggest me some biotech companies where fresher are hired.
