The amino acid sequence of a portion of a polypeptide is
-glu-met-tyr-trp-lys-.
i just need with part c
a. determine the mrna sequence encoding this polypeptide fragment. 5'-g-g-n-g-a-pu-a-u-g-u-a-py-u-g-g- a-a-pu-g-c-n-3'
b. determine the dna template strand sequence corresponding to the mrna above. 5' n-g-c-py-t-t-c-c-a-pu-t-a-c-a-t-py- t-c-n-c-c- 3'
c. determine the dna coding strand sequence corresponding to the template strand above.
express your answer as a sequence of nucleotides separated by dashes. use n to represent any nucleotide (a, t, c or g), pu to represent a purine( a, g), and py to represent a pyrimidine (c, t). example: c-t-pu-n-.

Cladistics is a way of classifying organisms by examining the characteristics of their ancestors and descendants and depicting the relationships in a cladogram. which of the following best describes a challenge in classifying organisms this way? a. there are millions of species on earth, and a cladogram is not a practical means for classifying all of them. b. it is impossible to tell which organisms are most closely related to each other using a cladogram. c. cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships. d. there is a limited number of ways to organize the information, so most cladograms end up looking very similar.
