Plasmids regulate their copy number to maintain a balance that doesn't burden the host cell. Copy numbers vary based on factors like plasmid size and culture conditions. Plasmids are classified as stringent or relaxed based on replication control. Various systems, including counter-transcribed RNAs

The stable maintenance of low-copy-number plasmids in bacteria relies on partition mechanisms that ensure proper positioning during cell division. Different from high-copy-number plasmids, which rely on random diffusion, low-copy-number plasmids require regulated partitioning mechanisms to prevent d

DNA, the hereditary basis of life, was first discovered by Friedrich Miescher in 1869. It consists of chromosomes, plasmids, and organellar DNA, collectively known as the genome. Genes, sequences of DNA, encode proteins and RNA, essential for an organism's functions. The genome is divided into chrom

Plasmids are replicons inherited extrachromosomally, existing as circular DNA molecules. They can be categorized as conjugative or non-conjugative based on transfer genes presence, and by copy number per cell. Linear plasmids and their maintenance mechanisms are also discussed, along with phenotypic

Complementary nitrogenous bases in DNA, pyrimidines (thymine, cytosine) and purines (adenine, guanine), store biological information through antiparallel strands. DNA, with non-coding regions, undergoes replication and transcription to RNA for protein synthesis. Nucleic acids, DNA, and RNA are cruci
