Briefly discuss the main contributions made by Louis Pasteur and Robert Koch in the development of modern day microbiology.

Cystic fibrosis is caused by autosomal recessive mutation. In European population one out of 10,000 babies is born with this disorder.what is the frequency of cystic fibrosis allele in European population assuming hardy Weinberg conditions are met ?

We transformed E coll cells with a plasmid modified to contain a 'virulence factor' which would allow growth on media containing the antibiotic

kanamycin (an). The plasmid confers constitutive resistance to ampicillin (Amp).

Assume you were given competent cells of known transformation efficiency (TE). Assume TE= 1x10[6] (note 10[6) means 10 to the power of 5).

You want to have about 1000 colonies on the P-200 plate. How many nanograms of plasmid should you use in the transformation reaction? Select

only one answer.

The heterozygoutes have heightened content of cystine in urine, homozygoutes - have

cystine stories in kidneys.

a) Determine the possible forms of cystic syndrome in children in the family, where one parent had cystic syndrome and another had heightened content of cystine in urine.

b) Determine the possible forms of cystic syndrom in children in the family,, where one parent had disease and another one had healthy heredity.
