Detailed explanation-1: -Two other amino acids occasionally appear in proteins. One is selenocysteine, which is found in Arachea, eubacteria, and animals. Another just recently found is pyrrolysine, found in Arachea.
Detailed explanation-2: -The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function. This is why mutations that alter amino acid sequence can affect the function of a protein.
Detailed explanation-3: -Abstract. Mitochondrial ribosomes (mitoribosomes) perform protein synthesis inside mitochondria, the organelles responsible for energy conversion and adenosine triphosphate production in eukaryotic cells.
Detailed explanation-4: -The Golgi apparatus and ER are key organelles needed for protein synthesis. The ER modifies and folds proteins, and the Golgi packages them for transport.
