What is the hallmark of all horizontal gene transfers?
|
|
Transfer of DNA between organisms of the same generation
|
|
|
Transfer of DNA from parent to offspring
|
|
|
The use of plasmids
|
|
|
Transfer of DNA using a virus
|
Explanation:
Detailed explanation-1: -In horizontal gene transfer, newly acquired DNA is incorporated into the genome of the recipient through either recombination or insertion. Recombination essentially is the regrouping of genes, such that native and foreign (new) DNA segments that are homologous are edited and combined.
Detailed explanation-2: -Bacterial conjugation, a process that involves the transfer of DNA via a plasmid from a donor cell to a recombinant recipient cell during cell-to-cell contact.
Detailed explanation-3: -In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells.
