As a plant scientist, you have been given 30 core collection of yam tubers; describe in details the molecular methods you will use to verify whether or not these accessions are from the same source.
a) During fasting, a fall in blood glucose signals the activation of which
key metabolic enzyme in adipocytes?
key metabolic enzyme in adipocytes?
What if a scientist believes that a virus is alive. How would you address this question: At this same convention your next dilemma is to inform other scientists of multicellular organisms dependency on both Prokaryotes and Protists. Where would you begin? Why would there be no multicellular animals without first Prokaryotes and Protists?

select and support the most appropriate response & explain why each of the incorrect statements is eliminated
3. Meiosis in an oocyte
a. creates 4 cells that are identical in size
b. results in qualitatively genetically different meiotic products
c. has an equational division in M I
d. segregates homologous chromosomes in M II
e. creates new allele combinations, along non-sister chromatids, during telophase I
5. Two genetically identical organisms express slightly different phenotypes for a given trait when
raised in different environments. This is an indication that
a. environmental components have a large effect on the expression of the phenotype
b. this phenotype is not multifactorial
c. the trait is determined by a single gene
d. the environment is equally important to the phenotype as the genotype
e. the phenotype is multifactorial but the genotype strongly influences the phenotype

a. During the isolation of TOL plasmid from Pseudomonas putida, it was observed that the concentration of the plasmid DNA per 50 mL of sample was extremely low. Describe a technique you could employ to increase the concentration of the TOL plasmid.
