Viruses are microscopic parasites responsible for a host of familiar – and often fatal – diseases, including the flu, Ebola, measles and HIV. They are made up of DNA or RNA encapsulated in a protein shell andcan only survive and replicate inside a living host, which could be any organism...
hepatitis, herpes, and even cancer. They are an extremely small foreign organism that invade healthy cells, and seek to wreak havoc in a healthy human or animal. Viruses are comprised of either RNA or DNA covered in a protein shell, and cannot reproduce on their own, so they rely on thei...
All viruses have: A. DNA B. a protein capsid C. a membranous envelope D. RNA Which of the following are part of a virus? (a) Ribosomes (b) Nucleus (c) Nucleic acid (d) Lipid envelope (e) Protein capsid. A virus is made up in ...
structure must be regular, with each protein subunit occupying a position at least approximately equivalent to that occupied by all other proteins of its class in the final structure (the principle of quasi-equivalence), although some viruses are now known to violate the principle of quasi-...
If these are the only two categories then that makes viruses non living because viruses are not prokaryote or eukaryote. Virsu have no organelles to from the fuction of a regular cell would. Viruses are a protein cased body called a capsid, and inside the 189 Words 1 Pages Satisfactory ...
What is a cheat? Cheats are individuals that exploit cooperators, by avoiding paying the cost of cooperation, while still benefiting from the cooperation of others5,6(Box1). Cheating can be thought of as a special form of parasitism, in which the parasite exploits a social trait, benefitting...
very small infectious particles that only replicate inside the living cells of a host organism central core of virus contains nucleic acid molecules made up of dna and RNA capsid of virus protein shell made of capsomers that covered and protect the genetic materiel envelope of virus additional pro...
Any of a heterogeneous class of agents that share three characteristics: (1) They consist of a nucleic acid genome surrounded by a protective protein shell, which may itself be enclosed within an envelope that includes a membrane; (2) they multiply only inside living cells, and are absolutely...
Viruses are very small structures that are not considered by scientists to be true living organisms. These structures contain a protein shell or capsule with genetic information inside of the capsule. Viruses rely on infecting living cells in order to reproduce themselves....
How does Or act as as a genetic switch between lysogenic and lytic cycles The lamda (lysogenic) or cro protein (lytic) can bind to any or all 3 of the operator sites and binding governs switch between lytic or lysogenic cycle What are the 3 operator sites located in the Or region?
