#Unit 3. Fundamental Processes

Replication starts at a specific origin in the circular duplex DNA. Initially, though, only one of the two parental strands (the H strand in mammalian mitochondrial DNA) is used as a

template for synthesis of a new strand. 

Synthesis proceeds for only a short distance, displacing the original partner (L) strand, which remains single-stranded,

#Unit 3. Fundamental Processes

SeqA mutants reduce the delay in remethylation at both oriC and dnaA. As a result, they initiate DNA replication too soon, thereby accumulating an excessive number of origins.
