While there are many ways to compare biochemical similarities in organisms, the molecular tree of life is based predominantly on similarities in what biological molecule?
A)DNA
B)proteins
C)ribosomal RNA
D)transfer RNA

Question

Quizplus · Accepted Answer

The molecular tree of life is based predominantly on similarities in ribosomal RNA (rRNA). rRNA is a component of the ribosome, which is responsible for translating genetic information into proteins. Its critical role in protein synthesis makes it a useful molecule for comparing biochemical similarities and evolutionary relationships between organisms.
