WebApr 11, 2024 · Antimicrobial resistance is a persistent challenge in human and veterinary medicine, which is often encoded on plasmids which are transmissible between bacterial … Plasmids with the same replicon are incompatible because they compete for the same replication control machinery within the cell. Most plasmids encode a negative regulation system involving antisense RNAs or iteronsthat inhibits replication when copy number in the cell is high, but allows replication when copy … See more Plasmid incompatibility also occurs because of plasmid partitioning (Schumacher, 2012). This concept is a little more complex than simply competing for replication control factors and tends to be more of a concern … See more If you want to clone two plasmids within the same bacterial cell, think about whether plasmid incompatibility will affect your plans.
