Scientists are now able to use the genetic code of organisms to find out more about their evolutionary history. How is this most likely to impact classification? Organisms once thought to be unrelated may be found to be related. Mode of nutrition of some organisms may change. Organisms that do not have a backbone may develop one. All multicellular organisms may be found to be prokaryotes

The right answer is b hydrogen bonds!

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
