It is found in DNA. It is used to build an organism's structures.
It allows parents and their young to have similar characteristics.
Explanation:
The genetic code can be defined as the set of rule that are used for encoding the genetic material in the form of DNA or RNA. These are translated in the protein by the living cells.
The genetic code is related to the tri-nucleotide sequences that are called as codons.
Each triplet of nucleotide is indicative of amino acid.
The specific amino acids are responsible for transferring the traits to humans. This causes the offspring to acquire similar traits as present in humans.
Sources such as diaries though not very reliable can be used if there are a large amount of them showing the same date and event. Historical books written about the event especially those closer to the time would be able to help determine that the date is accurate as well.
