Question
Chapter 13, Problem 1CCQ
Summary Introduction
To explain:
If random mutations are more likely to be beneficial or harmful.
Introduction:
The genetic material is all the living organism is the DNA (deoxyribonucleic acid). The DNA sequences are unique to the organisms. The changes in the DNA sequence of an organism are referred to as mutation.

- When an Avidian (with a genome size of 50 sites) reproduces with a 10% per site mutation rate, and if the number of mutations per genome is Poisson distributed, then what is the most likely outcome? Possible answers: 4 per genome is most likely, 5 per genome is most likely, 4 mutations per genome and 5 mutations per genome are equally likely, A number other than 4 and/or 5 mutations per genome is most likelyarrow_forwardThe genetic alteration responsible for sickle-cell anemia in humans involves: a transition mutation from A to G, substituting glutamic acid for valine in a-globin a transversion mutation from T to A, substituting valine for glutamic acid in b-globin a transition mutation from T to C, substituting valine for glutamic acid in b-globin a transversion mutation from G to C, substituting glutamic acid for valine in a-globin a frameshift mutation of one ATC codon, removing glutamic acid from b-globinarrow_forwardNine rII− mutants of bacteriophage T4 were used inpairwise infections of E. coli K(λ) hosts. Six of themutations in these phages are point mutations; theother three are deletions. The ability of the doubly infected cells to produce progeny phages in large numbers is scored in the following chart.1 2 3 4 5 6 7 8 91 − − + + − − − + +2 − + + − − − + +3 − − + − + − −4 − + − + − −5 − − − + +6 − − − −7 − + +8 − −9 −The same nine mutants were then used in pairwise infections of E. coli B hosts. The production of progenyphages that can subsequently lyse E. coli K(λ) hosts isnow scored. In the table, 0 means the progeny do notproduce any plaques on E. coli K(λ) cells; − meansthat only a very few progeny phages produce plaques;and + means that many progeny produce plaques(more than 10 times as many as in the − cases).1 2 3 4 5 6 7 8 91 − + + + + − − + +2 − + + + + − + +3 0 − + 0 + + −4 − + − + + +5 − + − + +6 0 0 − +7 0 + +8 − +9 −a.

- A geneticist isolates two mutations in a bacteriophage. One mutation causes clear plaques (c), and the other produces minute plaques (m). Previous mapping experiments have established that the genes responsible for these two mutations are 8 m.u. apart. The geneticist mixes phages with genotype c+ m+ and genotype c− m− and uses the mixture to infect bacterial cells. She collects the progeny phages and cultures a sample of them on plated bacteria. A total of 1000 plaques are observed. What numbers of the different types of plaques (c+ m+, c− m−, c+ m−, c− m+) should she expect to see?arrow_forwardA gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arg- tyr. A mutation in this gene has a G inserted after the second C in the strand. How will this mutation affect the phenotype? A:This will affect the phenotype because although most of the protein will be identical, the first amino acid will be different. B:This will not affect the phenotype because only the second amino acid is different from the original protein. C:This will not affect the phenotype because the protein will be identical to the original protein. D:This will affect the phenotvpe because all of the amino acids after the first one will be different from he original protein.arrow_forwardE. coli cells are simultaneously infected with two strains of phage λ. One strain has a mutant host range, is temperature sensitive, and produces clear plaques (genotype h st c); another strain carries the wildtype alleles (genotype h+ st+ c+). Progeny phages are collected from the lysed cells and are plated on bacteria. The following numbers of different progeny phages are obtained: Progeny phage genotype Number of plaques h+ c+ st+ 321 h c st 338 h+ c st 26 h c+ st+ 30 h+ c st+ 106 h c+ st 110 h+ c+ st 5 h c st+ 6 a.
