Mitochondria are able to produce their own

Mitochondria are semi-autonomous organelles that possess their own genetic material, known as mitochondrial DNA (mtDNA) [1][2]. This mtDNA contains the necessary information to encode specific components of the organelle, including ribosomal RNAs, transfer RNAs, and several essential polypeptides [1][2]. Consequently, mitochondria have their own internal protein synthesis machinery, including mitoribosomes, which allows them to produce some of their own proteins independently of the cell's nuclear DNA [1][3][4]. While they rely on the import of many proteins from the cytoplasm for their growth and function, their ability to perform intraorganellar translation is a defining characteristic [2]. They do not produce a nucleus, as they are organelles within a eukaryotic cell, nor do they produce chloroplasts, which are distinct organelles found in plants. Digestive enzymes are primarily associated with lysosomes rather than mitochondrial synthesis.
