Occurring in the nucleus ribosome mitochondrion , translation transcription is the process of making an RNA copy from a DNA template. The molecule then enters the cytoplasm. The process in which the mRNA sequence is converted into a sequence of amino acids is called translation transcription . In the cytoplasm, the nucleus ribosome mitochondrion reads the amino acid sequence and assembles the protein.
What results in the alteration of amino acid sequences during polypeptide formation in protein synthesis? A defective polypeptide may arise because of a change in its amino acid sequence Despite the change in amino acid sequence, the polypeptide formed will always be functional and will never cause a disease. The cell will have no other choice but to revert the faulty polypeptide into amino acids to undo its work. The nucleus, by means of its powerful enzymes, will eventually destroy the damaged protein so that it will not wreak havoc in the cell.
