the tree of life has been rearranged into three domains based on what evidence?

Sagot :

The tree of life has been rearranged into three domains based on DNA similarities. The linear order of nucleotides in DNA can be used to infer ancestry.

The three domains of the tree of life are Bacteria, Archaea and Eukarya.

Moreover, DNA is a double helix molecule composed of two long chains of nucleotides.

In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Adenine, Guanine, Cytosine and Thymine.

The level of conservation observed in the linear order of nucleotides in the DNA molecule can be used to recognize homology caused by ancestry (i.e., homology in the nucleotide sequence) between different types of organisms.
