Question 2

In the 1960s and 1970s,organisms were classified into five kingdoms,one of which was prokaryotes.In the 1980s,organisms were reorganized into three domains,with the prokaryotes split into Archaea and Bacteria,and all of the other four kingdoms lumped together into Eukarya.Why did this happen?

Accepted Answer

In the original classification,prokaryot

C) refer to substitutions in unrelated lineages. 
D) affect only certain amino acids. 
E) lead to transversions.

Question 4

Which of the following does not provide molecular evidence for evolution?

Accepted Answer

A) The 1,000-fold differences in nonsynonymous substitutions between some genes 
B) The existence of pseudogenes
