If scientists wanted to learn more about evolutionary history, they would study all but one of these molecules. Which biological molecule would NOT offer much information about the history of life?
Nucleic acids are among the four major Biomolecules, others being proteins, lipids and carbohydrates. Nucleic acids are divided into two; RNA and DNA.
By studying information about nucleic acids between organisms scientists are able to establish the evolutionary origin among organisms.
DNA molecules are fundamental molecules in organisms since they carry genetic information in living organisms. DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms.
Many organisms have distinct DNA sequences, however, animals may share some specific types of genes which are similar genetically in the sequences of DNA.
Proteins on the other hand are formed as a result of gene expression, therefore, proteins may be used to establish information about the gene sequences and more so the DNA. thus proteins may be used to establish evolutionary history among various organisms.
