10 Organisms can be classified based on homology, which is shared characteristics
inherited from a common ancestor. In the past, homologies were based on studies
of anatomical structures and patterns of embryonic development. In more recent
years, the use of molecular biology techniques has allowed homologies to be
compared at the level of nucleotide sequences. Nucleotide sequence comparisons
are possible because all organisms share which of the following?
F DNA bases
G Cellular organelles
H Division of the nuclear chromosomes
J Types of proteins needed for cellular functions
