Answer 1

The correct answer is Nitrogen.

Key Points

Nitrogen is a fundamental component of amino acids, which are the building blocks of proteins.
It is essential for the formation of peptide bonds that link amino acids together to form proteins.
Nitrogen is a major constituent of the genetic material, DNA and RNA, which directs protein synthesis in cells.
Approximately 78% of the Earth's atmosphere is composed of nitrogen gas (N2), making it abundantly available for biological processes.

Additional Information

Amino Acids
- They are organic compounds that combine to form proteins.
- There are 20 different amino acids that can be arranged in various sequences to create a vast array of proteins.
Peptide Bonds
- These are covalent bonds formed between the amino group of one amino acid and the carboxyl group of another.
- Peptide bonds link amino acids together in a chain, forming polypeptides or proteins.
DNA and RNA
- DNA (Deoxyribonucleic Acid) contains the genetic blueprint for the synthesis of proteins.
- RNA (Ribonucleic Acid) is involved in translating the genetic code into proteins during protein synthesis.
Protein Synthesis
- This is the process by which cells generate new proteins, involving transcription (from DNA to mRNA) and translation (from mRNA to protein).
- Ribosomes, tRNA, and various enzymes play critical roles in this complex process.
Atmospheric Nitrogen Fixation
- Although nitrogen is abundant in the atmosphere, most organisms cannot use it directly and depend on nitrogen fixation.
- Certain bacteria and archaea convert atmospheric nitrogen (N2) into ammonia (NH3), making it available for biological use.
