Provide each team with a copy of "The Hunt for mtDNA" student handout. Explain to students what mtDNA is, how it differs from nuclear DNA, and how it is inherited (see Activity Answer for more ...

Mitochondrial diseases are a heterogeneous group of disorders with varying clinical features caused by impaired function of the mitochondrial respiratory chain. The underlying cause can be gene ...

A high-throughput single-cell single-mitochondrial genome sequencing technology known as iMiGseq has provided new insights into mutations of mitochondrial DNA (mtDNA) and offers a platform for ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

One study reported 8 live births from 22 women with pathogenic mtDNA variants who underwent mitochondrial donation through pronuclear transfer. None had signs of mitochondrial disease and heteroplasmy ...

A new study from deCODE genetics uses pedigrees and sequence data from 64,806 Icelanders to shed light on the rate and nature of mutations in mitochondrial DNA (mtDNA) and the peculiar dynamics of its ...

The vast majority of our DNA—the chromosomes in the nucleus of each cell—is just what you’d expect: a mix of genetic material from both mother and father. But mitochondria are an exception. They ...

Understanding the relationship between mtDNA and animal growth could provide valuable information for selective breeding in aquaculture. However, the complex interactions between genetics and ...

You are a forensic scientist recruited to help solve a long-standing "missing persons" case. Mitochondrial DNA, or mtDNA for short, is the key to your success. Take careful notes as your teacher ...

When a four-year-old boy was brought to the Cincinnati Children’s Hospital Medical Center with fatigue, muscle pain and muscle weakness, doctors suspected there might be something wrong with his ...
