Suppose that you have discovered two different transposable elements (A and B) in yeast and you inserted an intron into each of the elements. Following transposition of each transposable element, you examine the transposed elements to determine if the intron is present. You notice that the intron is present in […]

The mediam molecular weight of eukaryotic proteins is about 40,000 daltons. A few proteins are much larger, such as a muscle cell protein called titin, which has a molecular weight of 3,000,000 daltons. A) Estimate how long it will take a muscle cell to translate an mRNA coding for a […]

Consider a mainland-island migration scenario where two alleles are segregating and the observed frequencies of heterozygotes are such that H=.32 for the mainland and H=.5 for the island. (These are the values of heterozygosity) What are Pisland and Pmainland? Assume Hardy-Weinberg equilibrium. Equation given was Pisland = Pmainland + ( […]
