Function of mitochondrial DNA ?
Human mitochondria contain two to ten copies of a small circular double-stranded DNA molecule that makes up approximately 1% of total cellular DNA.The majority of the peptides in mitochondria (about 54 out of 67) are coded by nuclear genes.The rest are coded by genes found in mitochondrial (mt) DNAThis mtDNA codes for mt ribosomal and transfer RNAs and for 13 proteins that play key roles in the respiratory chain.
Encodes proteins of cell membrane
Encodes proteins of respiratory chain
Helps in cell replication
Formation of rRNA
