  1. Plasmid - Wikipedia

    Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms. In the laboratory, plasmids may be …

  2. Plasmid - National Human Genome Research Institute

    1 day ago · Scientists use recombinant DNA methods to splice genes that they want to study into a plasmid. When the plasmid copies itself, it also makes copies of the inserted gene. A …

  3. Plasmid | DNA replication, genetic engineering, cloning | Britannica

    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 …

  4. What Is a Plasmid in Biology? Its Function and Uses

    Aug 23, 2025 · Understand plasmids, from their natural biological roles to their critical use as versatile tools in modern genetic engineering and scientific research.

  5. What is a Plasmid? | Ask A Biologist

    Apr 12, 2010 · Plasmids are autonomous molecules and exist in cells as extrachromosomal genomes, although some plasmids can be inserted into a bacterial chromosome, where they …

  6. What Do Plasmids Do? From Nature to Biotechnology

    Plasmids are small, extrachromosomal DNA molecules found predominantly in bacteria and some eukaryotic organisms like yeast. They exist as closed loops of double-stranded DNA, …

  7. What Is Plasmid DNA? Understanding Its Role in Biotechnology

    Dec 30, 2025 · Plasmid DNA is a small, circular piece of genetic material in bacteria, and discover its vital role in genetic engineering and biotechnology research.

  8. Plasmids are independent DNA loops used to clone DNA

    Plasmids carry only a few genes and exist independently of chromosomes, the primary structures that contain DNA in cells. Able to self-replicate, plasmids can be picked up from the …

  9. 10: Plasmids - Biology LibreTexts

    Plasmids are small, circular DNA molecules that replicate independently of the chromosomes in the microorganisms that harbor them. Plasmids are often referred to as vectors, because they …

  10. 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.
