For questions 13-17, match the items to the best answer from the I Key: not harmful! sometimes harmful: usually harmful I point mutation that changes one codon of a gene frameshift mutation that changes all following codons point mutation that changes a codon into a \"stop codon movement of a transposon into the middle of a gene point mutation that does not change the amino acid specified the codon Which of the following is not useful in creating recombinant restriction endonuclease DNA ligase RNA polymerase plasmid Genome comparisons may yield information about which of the following? evolutionary relationships between organisms changes in genes over evolutionary history links between genes and disease All of these are correct.

Solution

13. A point mutation that changes one codon of a gene is sometimes harmful.

14. Frameshift mutation that changes all the following codons i.e. Insertion/deletion is usually harmful.

15. A point mutation that changes one codon to stop codon is usually harmful because incomplete protein will not function which will be disastrous.

16. Movement of a transposon in the middle of the gene is sometimes harmful.

17. Point mutation that does not change the amino acid specifies the codon i.e. silent mutation is sometimes harmful causing diseases.

18. RNA pol not used in creating recombinants.

19. d. all of these are correct.
