Unformatted text preview: to serine. Or correct answer if you take the complementary RNA strand and translate that: A. UAA GGC CCC AAA UUU CGG GUU Stop Glycine Proline Lysine Phenylalanine Arginine Valine B. UGA GGC CCC AAA UUU CGG GUU Stop Glycine Proline Lysine Phenylalanine Arginine Valine The mutation is in the 1stth codon, second position, is a point mutation in the DNA strand of T to a C, a synonymous one and is a transition and results in a stop to a stop codon. 5) Children of older fathers are born with more mutations than children of younger fathers. Explain in two sentences, why this is the case (2 points). Children of older fathers are born with more mutations because the sperm cell lines giving rise to sperm cells continue to divide after puberty, leading to the accumulation of mutations over the lifespan of men. Thus, children born to older men have these genomes in their genomes as a result of mutation accumulation in male gamete cell lines. 6) A parental population of 200 fruit flies (Drosophila) is comprised of 50 red eyed (A1 A1), 100 pink eyed (A1 A2), and 50 white eyed (A2 A2) flies. Calculate the genotypic and allele frequencies of each eye color type in this population (2 points). Genotypic Frequencies: p2 = 0.25 2pq = 0.50 q2 = 0.25 Allele Frequen...
