Answer: DNA was the first genetic material.
Explanation:
The genetic code is essentially the same in all the organism. This states that the similar organism can have similar genes in them that codes for the similar proteins hence, called as similar organism.
The genetic material is chemically made of nucleotide which is either being synthesized in the body or being obtained from the environment similar to that of amino acids.
If the genetic code is same one organism descend from the other organism.But these statement does not supports that DNA was the first genetic material to found in living beings.
Fungi are eukaryotic and saprophytic microorganisms that grow on dead and decaying matter. These organisms release digestive enzymes that break down leaves, fruit and other organic material into simple molecules. These can grow on wood, clothes, food, fruits, leather shoes, etc by breaking down complex organic matter into simpler forms with the help of extracellular digestive enzymes such as cellulases, proteases, phosphatases, etc.
MRSA is a kind of staph that can't be killed by antibiotics.
