Mitochondria and their 16.5-kb circular genomes (mtDNA) undergo constant turnover in arrested primary oocytes for decades in humans (1, 2).Frequent DNA replication and lack of efficient DNA repair mechanism in the mitochondrion contribute to a mutation rate that is ∼10-fold higher than that of the … WebA tRNA contains hairpins as well, though the hairpins play different roles in the two cases. In transcription termination, the hairpin causes the RNA polymerase to stall and the …
