What are the three mechanisms for horizontal gene transfer? a. horizontal gene transfer b. vertical gene transfer c. transformation d. none of these answers e. horizontal gene transfer, vertical gene transfer and transformation Some bacteria can transfer genes across biological domains, General transfer of genes between cells using bacteriophage particles, transfer only a few closely linked genes between cells, Usually is a lytic phage that sometimes uptakes host DNA instead of phage DNA and when phage infects another cell it inserts the host DNA, P22 phage DNA infects a host cell and makes subunit components for more phage. because horizontal gene transfer appears to have been common among early life forms.
