The experimental approach taken in current biological investigations presumes that

#SCPH06 I Botany
  1. simple organic compounds can be synthesized in the laboratory from inorganic precursors, but complex organic compounds like carbohydrates and proteins can only be synthesized by living organisms.
  2. living organisms can be understood in terms of the same physical and chemical laws that can be used to explain all natural phenomena.
  3. although a life force, or vitalism, exists in living organisms, this life force cannot be studied by physical or chemical methods.
  4. living organisms are composed of the same elements present in nonliving things, plus a few special trace elements found only in living organisms or their products.

At high salt concentrations, the mRNA containing poly(A) tails binds to the complementary oligo(dT) molecules of the affinity column, and so, mRNA will be retained; all other RNA molecules can be washed through the column by further high salt solution. finally, the bound mRNA can be eluted by using

The interaction of selection and inbreeding in determining the incidence of autosomal recessive diseases. Consider a gene in which recessive mutations occur at a rate of 10-5. Assume a selective disadvantage S of 0.4 in homozygotes for the recessive allele. What is the frequency of the recessive allele (q). And calculate the incidence of the disease. Assume random mating.
