  • Plasmid - Wikipedia
    Diagram of a bacterium showing chromosomal DNA and plasmids (Not to scale) A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently
  • Plasmid - Definition, Types and Functions - Biology Dictionary
    It replicates independently of chromosomal DNA Plasmids are mainly found in bacteria, but they can also be found in archaea and multicellular organisms Plasmids usually carry at least one gene, and many of the genes that plasmids carry are beneficial to their host organisms
  • Plasmid - National Human Genome Research Institute
    A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms Plasmids are physically separate from chromosomal DNA and replicate independently They typically have a small number of genes — notably, some associated with antibiotic resistance — and can be passed from one cell to another
  • Plasmids- Definition, Properties, Structure, Types, Functions, Examples
    Plasmids are small circular DNA fragments, double-stranded, self-replicating extra chromosomal structures found in many microorganisms The term Plasmid was coined by Joshua Lederberg in 1952 Plasmids are important as genetic tools, which are used to introduce, manipulate or delete certain genes from the host cell
  • DNA replication, genetic engineering, cloning - Britannica
    plasmid, in microbiology, an extrachromosomal genetic element that occurs in many bacterial strains Plasmids are circular deoxyribonucleic acid (DNA) molecules that replicate independently of the bacterial chromosome They are not essential for the bacterium but may confer a selective advantage
  • Plasmids 101: What is a plasmid? - Addgene
    At their most basic level, plasmids are small circular pieces of DNA that replicate independently from the host's chromosomal DNA They are mainly found in bacteria, but also exist naturally in archaea and eukaryotes such as yeast and plants
  • Plasmids: Structure, Types, and Their Role in Gene Transfer
    Explore the essential role of plasmids in gene transfer, their diverse structures, and types, enhancing our understanding of genetic exchange Plasmids are small, circular DNA molecules that exist independently of chromosomal DNA in bacteria and some eukaryotes
  • plasmid plasmids | Learn Science at Scitable - Nature
    Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance
  • What is a Plasmid? - Ask A Biologist
    Plasmids A plasmid is an independent, circular, self-replicating DNA molecule that carries only a few genes The number of plasmids in a cell generally remains constant from generation to generation
  • Plasmids - Definition, Structure, Functions, Examples - Biology Notes . . .
    Plasmids are small, extrachromosomal DNA structures found primarily within bacterial cells, distinct from the primary chromosomal DNA Unlike the chromosomal DNA that encompasses the essential genetic blueprint of the organism, plasmids are typically circular and replicate autonomously
