How many circular dna e. coli have per cell
WebThe single circular chromosome of E. coli contains about five million DNA base pairs, only 1/600th the haploid amount of DNA in a human cell. In addition, the E. coli cell may contain small, circular DNA molecules (1,000 to 200,000 base pairs called plasmids, which also carry genetic information. WebFeb 18, 2024 · After optimizing the vector, pRC09 was constructed to produce a circular ssDNA of 4974 nts (5 kb) in E. coli . The cells of DH10β and DH5α harboring pRC09 were disrupted using cell lysis solution (CLS), and the target sequence amplified to verify the circular ssDNA yield. This result showed that a longer ssDNA could be produced in vivo …
