Answer:
D
Explanation:
Common ancestors has nothing to do with the theory of evolution
The answer is UAC.
In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). So, when in the process of translation, anticodons of tRNA pairs with codons of mRNA, the complementary bases will pair. So, adenine in tRNA will pair uracil in mRNA (A → U), uracil in tRNA will pair adenine in mRNA (U → A), and guanine <span>in tRNA will pair cytosine in mRNA (G </span>→ C):
tRNA: A U G
mRNA: U A C
B. by the sharing of electrons
Answer choices A and C are incorrect because covalent bonds form as a result of electrons (protons are kind of irrelevant). Answer choice D is incorrect because it describes an ionic bond.
