Also nature, for example there are some plants and trees that are made to live in colder weather so when it becomes hot they will die and not grow in this area anymore becuase they cannot just get up and walk away as animals can.
Explanation:
<span>Proteins are large biomolecules that are made up of long chains of building block molecules called amino acids. Each amino acid folds to form a protein with a specific cellular function.
Nucleic acid is basically DNA & RNA. DNA is the genetic information that contains all the information one needs to live. RNA stands for ribonucleic acid and has a variety of roles.
When comparing them, they actually don't look at all similar when looking at the large molecules or the 'building blocks'. But, they're both made up of mostly carbon, nitrogen, hydrogen and oxygen. The elements mentioned are assembled in different ways for both Proteins & Nucleic acid. The major similarity between them is that with the protein production DNA and RNA contain all the information that a cell uses to make protein.
</span><span>Their overall interactions can be summed up by the central dogma of molecular biology:
DNA --transcription--> RNA --translation--> Proteins
