Question

Identify the stages of mitosis marked with arrows. Use the following answers to complete After your visit to the tanning salon what DNA repair mechanism is doing its jobs? Shown below is a portion of a wild-type polypeptide. If the mutant polypeptide resulted form a single nucleotide change, identify the mutation. The "..." refers to additional acids. A transition occurs in the third position of the DNA codon ACC. The would result in which of the following mutations. A transversion occurs in the second position of DNA codon ACC, This would result in which of the following mutations. If a single transition occurs at any position in the codon for the amino acid tryptophan (TRP), how many different amino acid substitutions would be possible? A region of DNA with tandem repeats of the sequence CTC will be prone to A DNA sequence contains the base hypoxanthine. As we all know hypoxathine is not a normal base. What mechanism gave rise to the hypoxanthine?

Explanation / Answer

16-d telophase

17-b metaphase

18-a excision repair

19-b transversion

20-a.silent

21-e transversion leads to point mutations so it may be missense or nonsense mutations.

22-a.1

23-b missense mutations

24-b.deamination
