What is a portal, horizontal portal, and vertical portal? What is the difference between a portal and a site? Any place that one can visit on the world wide web is a site, more specifically, a website. A website with large number of links to other websites is a portal. It is normally used as an entry point for most people accessing the world wide web. A portal with information and links to websites featuring diverse subjects is a horizontal portal e.g. www.indiatimes.com and www.mantraonline.com. A portal having links and information focused on a particular subject is a vortal or a vertical portal e.g. www.quicken.com, www.nuptialknots.com, or www.jguru.com.
Horizontal gene transfer is defined to be the movement of genetic material between bacteria other than by descent in which information travels through the generations as the cell divides. Transduction-the transfer of DNA by phage requires that the donor and recipient share cell surface receptors for phage binding and thus is usually limited to closely related bacteria; the length of DNA transferred is limited by the size of the phage head.
