Document Summary
Refers to the exchange of nucleotide sequences often occurring between homologous sequences. Cells with dna molecules that contain new nucleotide sequences vertical gene transfer organisms replicate their genomes and provide copies to descendants. Many prokaryotes can acquire genes from other microbes of the same generation. Donor cell contributes part of its genome to a recipient cell. Typically a recipient cell inserts part of donors dna into its own chromosome making it a recombinant cell: transformation, transduction donor cell transfers portion of its dna to a recipient cell, conjugation. The transfer of genetic information between organisms in the same generation is called horizontal gene transfer. When recipient obtains portion of donors dna it is called a recombinant cell. Transformation: recipient cell takes up dna from the environment once a bacteria dies, cells that have the ability to take up dna from their environment are competent.
