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.
The statement that cannot be logically assumed from the statement that genetic code is essentially the same for all organisms is: DNA was the first genetic material.
GENETIC CODE:
- Genetic code is used to describe a set of rule that explains how nucleotides of a DNA molecule are used to synthesize proteins.
- Genetic code is the sum of all codons that encode amino acids in the genome. One of the characteristics of the genetic code is that it is essentially the same for all organisms.
- This characteristics assumes the following statements:
- All organisms have a common ancestor
- A gene from an organism could theoretically be expressed by any other organism
- Related organisms have many similar genes
- All organisms must either manufacture nucleotides or obtain them from their environment.
- Therefore, the statement that cannot be logically assumed from the statement that genetic code is essentially the same for all organisms is: DNA was the first genetic material.
