Consider the expression of different genes in the B-globin locus. During different times in development, a different version of the gene is predominantly expressed (see graph). These are the Greek letters used in the graph. Please write out their name as your answer to the questions below. x = alpha, ß beta, & epsilon, Ç= zeta, 8 = delta, y = gamma = Blank #1: Which 2 forms are most expressed at the stage in development indicated by (1)? Phrase your answer as: (most abundant form with greek letter written out) and (second most abundant form with greek letter written out)... no quotes, see example below ex. you would say, "alpha and beta" NOT a and B Blank #2: Which 2 forms are most expressed at the stage in development indicated by (2)? Phrase your answer as: (most abundant form with greek letter written out) and (second most abundant form with greek letter written out)... no quotes, see example below ex. you would say, "alpha and beta"NOT a and B Blank #3: Which 2 forms are most expressed at the stage in development indicated by (3)?
