Mendel did experiments in which he kept track of the inheritance of seed texture (wrinkled or smooth). first he created true-breeding lines: parents with smooth seeds produced offspring with smooth seeds, and parents with wrinkled seeds produced offspring with wrinkled seeds. when he crossed wrinkled and smooth peas from these true-breeding lines, all of the offspring were smooth.

(1) which trait is dominant?
(2) what happened when he crossed members of the f1 generation? (in terms of phenotypic outcomes and genotypic outcomes).
(3) what would have happened had he crossed members of the f1 generation with individuals from a true-breeding line (the f0 generation) with smooth seeds? (again, in terms of phenotypic outcomes and genotypic outcomes).
(4) what about crosses between the f1 generation and the wrinkled-seed true-breeding line? (once more, in terms of phenotypic outcomes and genotypic outcomes).

American scientist, linus pauling, was one of many scientists racing to discover the molecular structure of dna. pauling initially thought that the molecule was a triple helix. later, james watson and francis crick unveiled their double helix model, which turned out to be an accurate description of the molecule's shape. why did watson and crick succeed when pauling failed?

You are studying several alleles of an e. coli helicase gene. one allele, called rsr, confers resistance to rs2014, an antibiotic that works by inhibiting helicase activity. bacteria with the rss allele are sensitive to rs2014. another allele, called ts-, produces a temperature sensitive mutation of the helicase. in bacteria with the ts- allele, helicase is inactivated at 42 °c but functions normally at 37 °c. helicase functions normally at both temperatures in bacteria with the ts allele. you obtain the following data while testing four strains of e. coli at different temperatures and doses of rs2014. each number represents the percentage of maximal dna synthesis. based on this data, assign the appropriate genotype to strains a–d in the spaces provided
