How does genetic evidence supports the idea that all organisms are related? A) Some organisms have a DNA and some do not
B) Each organism has DNA made from different molecules
C) Each organism on Earth has DNA made from the same nitrogen bases in different sequences
D) Every organism on Earth has the same sequence nitrogen bases in their DNA

Explanation:

patterns found in all organisms. Additional genetic information conclusively supports the relatedness of life and has allowed scientists (since the discovery of DNA) to develop phylogenetic trees: a construction of organisms evolutionary relatedness. It has also led to the development of molecular clock techniques to date taxon divergence times and to calibrate these with the fossil record.
