Why protein biosynthesis is considered one of the most important forms of plastic metabolism.

The most important process of plastic metabolism is protein biosynthesis. Protein biosynthesis is carried out in all cells of prokaryotes and eukaryotes. Information on the primary structure (amino acid order) of a protein molecule is encoded by a nucleotide sequence in the corresponding section of the DNA molecule — the gene. A gene is a section of a DNA molecule that determines the order of amino acids in a protein molecule. Therefore, the order of amino acids in a polypeptide, i.e. its primary structure, on which in turn all other structures, properties and functions of the protein molecule depend. The system for recording genetic information in DNA in the form of a specific nucleotide sequence is called the genetic code. Those. the unit of the genetic code (codon) is a triplet of nucleotides in DNA or RNA that encodes a single amino acid. In total, the genetic code includes 64 codons, of which 61 are coding and 3 non-coding (termination codons indicating the end of the translation process).

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
