Which one of the components of virus' structure is optional?
The envelope (without it the virus is "Naked") and spikes Remember viruses do not have any organelles (ex: ribosomes)

300
What anti-viral drug inhibits Herpes replication?
What is Acyclovir.
300
What is the key difference between an envelope and a cell membrane? Which one does a virus have?
Viruses have an envelope, which is not active in transporting materials in and out. Lipids have transmembrane proteins and selective permeability- they are "active".
300
Which of the following conditions likely existed on earth when the probionts first appeared? a.The surface of the earth was likely totally covered by molten lava (no liquid water) b.High levels of oxygen in the atmosphere caused oxidation of newly formed building blocks c.Abundant levels of inorganic reductants such as FeS, H2S, and H2 were available and could have contributed to early fueling systems d.More than one of these answers is correct
c.Abundant levels of inorganic reductants such as FeS, H2S, and H2 were available and could have contributed to early fueling systems

Name and explain the three types of horizontal gene transfer.
Conjugation: Direct attachment via pili (Type IV) Transformation: From the environment (ex. picking up DNA from lysed cells) Transduction: Phage accidentally packages bacterial DNA and transfers to another bacteria
