For the aforementioned reasons, mitochondria preserve several remnants of their bacterial origin, among them, the presence of a small genome, which in humans is a circular molecule of 16,600 base pairs, which we will herein refer to as mitochondrial DNA mtDNA.
Por eso, las mitocondrias actuales conservan remanentes de su origen bacteriano, entre otros, la presencia de un pequeño genoma que en el humano es una molécula circular de 16,600 pares de bases que aquí denominaremos DNA mitocondrial DNAmt.
