Synchronous termination of replication of the two chromosomes is an evolutionary selected feature in Vibrionaceae
Fig 3
Replication start and end control models.
(A) Scheme of replication patterns of Vibrio cholerae, replication start and end control model. Circles represent chromosomes, arrows the length and timing of DNA replication. Black stands for Chr1, red for Chr2. Grey dashed lines show start and end of DNA replication of V. cholerae Chr2. Green dashed lines indicate the corresponding expected start and end of DNA replication of Chr2. (B) Scheme of expected MFA plots of exponentially growing cells. Black lines represent regression lines for values of Chr1, red lines of Chr2. Dashed lines as in (A).
