got it thanks recessive- phenotype is expressed and not present with dominant allele epistasis is the interaction of gene loci and masks the expression of another gene loci
filter (to remove fungus) ; fungus washed (to remove penicillin) ; continuous countercurrent / chemical extraction ; concentration ; addition of potassium ions ; precipitate crystals / (potassium) salts ; solvents used to purify penicillin ; AVP ; e.g. dried, some are chemically modified, 99.5% pure
and in response to your question I have no idea? because no lactose is present? idk
It is because the bacteria will take up the lactose and break it down into glucose (remeber E.coli in the Lac Operon?) This means that there is no lactose present anymore. :')

correct again! im out for the night, probably be back tomorrow... you should relax soon! good luck with revision and exams! seeya
Describe the advantages to microorganism of the capacityto take up plasmid DNA from the environment:
more resistance, mutation ,pass on to offspring advatageous alleles , can become resistant to anitibioitic conjugation , can cause more bacterias to divide?
