Are Egg Cells in Aging Primates Protected From Mutations? - Technology Networks

Mutations to mitochondrial DNA in aging rhesus monkey egg cells accumulate over time but plateau at a certain age, indicating there may be a protective mechanism that keeps the mutation rate lower than in non-reproductive cells.

New mutations occur at increasing rates in the mitochondrial genomes of developing egg cells in aging rhesus monkeys, but the increases appear to plateau at a certain age and are not as large as thos… [+5912 chars]
