    Study Notes

    Restriction Enzymes

    • Restriction enzymes cut DNA molecules at specific sequences called restriction sites, producing DNA fragments.
    • They produce 'sticky ends' that can bond with complementary ends, allowing for the connection of DNA fragments.
    • The primary function of restriction enzymes in the context of gene manipulation is to cut DNA molecules at specific sequences.

    Gene Cloning

    • The purpose of gene cloning is to produce multiple copies of a specific gene or DNA segment.
    • Gene cloning involves the insertion of a foreign gene into a plasmid to create recombinant DNA.
    • The technique used to make multiple identical copies of a gene or DNA segment is gene cloning.

    Plasmids

    • The role of plasmids in DNA cloning is to provide a vector for the insertion of a foreign gene.
    • A bacterial plasmid is used to replicate the gene of interest, producing multiple copies of the gene.
    • The function of a bacterial plasmid in DNA cloning is to act as a vector for gene replication.

    Polymerase Chain Reaction (PCR)

    • The primary function of PCR is to make multiple copies of a specific target segment of DNA.
    • PCR is a technique used to produce many copies of a specific target segment of DNA.

    DNA Technology

    • The term that describes the direct manipulation of genes for practical purposes is genetic engineering.
    • Genetic engineering refers to the manipulation of organisms or their genetic components to make useful products.
