Protein synthesis, Protein synthesis is a process to synthesize amino acid in polynucleotide chain. Information encoded in genes determines the final expression of amino acid sequence in polynucleotide.
Biological Central Dogma
The correlation between DNA and RNA in heredity, cell structure, and Cell activities are summarized in central dogma concept. The concept can be interpreted as "the source of all information" ' It can be noted in the Following scheme.
The scheme of central dogma
The concept above explains that the primary key in protein synthesis is DNA, the genetic material of a cell. The arrow directing leftward means that the DNA is able to reproduce itself through replication. The Arrow directing rightward means that the DNA is able to monitor RNA Synthesis (through transcription process) and protein synthesis (through translation process).
Protein synthesis involves transcription and translation processes.
DNA replication occurs in the cell nucleus when preparing mitosis and meiosis divisions. Without replication, the daughter cell will not obtain any information required to continue its life. The result of transcription process is the information of dRNA strand which is the copy of DNA strand.
