Chromosomes in bacteria
WebBacteria have just a single chromosome, arranged in a ring. Species also differ in how chromosomes specify sex. In birds, the sex chromosomes are called Z and W. Females are ZW and males are ZZ. The tiny roundworm C. elegans has just one type of sex chromosome called X. WebBacterial chromosomes have a single, unique replication origin (named oriC ), from which DNA synthesis starts. This study describes methods of visualizing oriC regions and the chromosome replication in single living …
