Organisms can be classified based on homology, which are shared characteristics inherited from a common ancestor. 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 of the following?

A	DNA bases used in the genetic code
B	Cellular organelles for photosynthesis
C	Nucleus protected with nuclear membrane
D	Asexual reproductive abilities

Explanation:

Detailed explanation-1: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.

Detailed explanation-2: -Homologous features If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.

Detailed explanation-3: -Homologous structures If two or more species share a unique physical trait they may all have inherited this trait from a common ancestor. Traits that are shared due to common ancestry are homologous structures. The similar bone arrangement of the human, bird, and whale forelimb is a structural homology.

Detailed explanation-4: -Homology is the relationship between structures or DNA derived from the most recent common ancestor. A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates.
