SUMMARY
Human mitochondrial DNA (mtDNA) contains 37 genes that encode 13 proteins essential for oxidative phosphorylation, all within approximately 16,500 base pairs. In contrast, human nuclear DNA comprises about 3 billion base pairs and encodes around 20,000 proteins, with a significant portion being non-coding sequences. This highlights the limited but critical role of mitochondrial DNA in cellular energy production compared to the extensive coding capacity of nuclear DNA.
