Question asked describe the reason why viruses are termed as “particles” and not as “cells” and why they are categorized as “obligate parasites ” of host cells? Introduction: Virus is a microscopic living particle. Organization of viral genetic material is packed by the protein coat called as capsid. Genetic material of virus is double stranded or single stranded, which is either RNA or DNA. Virus has the ability to infect all living forms, which include bacteria, archaea, and they can also infect plants as well as animals.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
