22. The more amino acids that an organism has in common, both type and order, indicates the closer the relationship. The same is true for nucleotides. Compare the biochemical data above. Which organism is most closely related to the lizard? Why? 23. Which organism is most closely related to the Dolphin? Why? 24. How do you think different amino acid sequences would effect organisms? Explain your answer.

Step 1
The question mentions that the more amino acids (and their order) two organisms have in common, the closer their evolutionary relationship is. This principle also applies to nucleotides, the building blocks of DNA and RNA. This concept is fundamental in molecular Show more…

7. In general, about what percent amino acid sequence similarity would proteins need to have in order to be considered homologous? Where did you find the information to answer this question (site reference): (pts) 8. From the information you obtained (by analyzing the amino acid sequence of N-methyltransferase), would you conclude that the N-methyltransferase found in Coffea arabica, Camellia sinensis, and Theobroma cacao are homologous or analogous? Please explain your answer in detail, in your own words: (pts) 9. In your own words, please explain why species that are not closely related evolve similar traits: (Zpts)
