Proteins are synthesised by ribosomes which are RNA protein complexes.
Where are proteins synthesised inside the cell: RER is responsible for protein production (Rough Endoplasmic Reticulum). The ribosomes that are linked to the RER are responsible for protein production. Ribosomes are formed in the cytoplasm as well as the chloroplast of the mitochondria. The RNA found in ribosomes plays an important role in the synthesis of proteins and is essential for this process. The translation is used to refer to this synthesis since the protein complex is generated from the amino acid and the amino acid structure is deciphered from genes during this process.
Transcription is the process by which genetic instructions contained in DNA are transferred to messenger RNA (mRNA) in the nucleus. It consists of three steps: the initialization, the elongation, and the ending.
