Web7 jul. 2024 · Is bacterial chromosome replication bidirectional? Bacterial chromosomal replication occurs in a bidirectional manner, and has been investigated both genetically and autoradiographically, whereby results provide clear evidence for bidirectional replication in E. coli. What does bacterial chromosome consist of? WebDNA replication is the process of making new copies of double-stranded DNA by synthesizing new DNA strands. DNA replication is a bidirectional process as the strands of DNA are antiparallel, i.e., 3'-5' in one strand and 5'-3' in the other direction. The DNA polymerase synthesizes the DNA in 5'-3' direction. WebEscherichia coli (E. coli) bacteria has been wellstud ied experimentally (Fig. 1), which makes it possible to make a detailed mathematical description of all the stages of the induced mutation process with the pur pose of revealing new regularities.
