Summary Introduction
Virus a prokaryotic microscopic organism measures about 20 – 300 nanometers which are mostly infectious agents. Viruses are pathogenic to humans, plants and animals cause deadly disease. The virus contains single-stranded RNA as their genetic element instead of DNA. The virus needs a host cell in order to replicate itself.

According to origin-of-life scenarios proposed by William Martin, Michael Russell, and Theodor Diener, the first self-replicating genetic molecules were most similar to: double-stranded RNA viruses single-stranded RNA virusoids single-stranded DNA viruses double-stranded DNA viruses single-stranded RNA viroidsarrow_forward
- Students are debating about differences between viruses and cells. Which student’s argument is MOST correct using evidence from the diagrams? A. Diagram 1 represents a virus and Diagram 2 represents a cell because viruses do not have nucleic acids but cells do. B. Diagram 1 represents a cell and Diagram 2 represents a virus because a virus has nucleic acids and cells do not. C. Diagram 1 represents a cell and Diagram 2 represents a virus because viruses have a protein capsid while cells have a lipid membrane. D. Diagram 1 represents a virus and Diagram 2 represents a cell because cells have ribosomes to make their own proteins and viruses do not.arrow_forwardAre viruses considered as cells? why or why not?arrow_forwardHow do retrovirus assemble new viral progeny? a. Viral RNA is copied into DNA, then integated into the host genome and transcribed ans translated b.Viral DNA is copied into RNA, then integated into the host genome and transcribed and translated c. Retroviruses use the same machinery as prokaryotes and follow the same process to make RNA d. Retroviruses have an RNA genome instead of DNA but use all of the same enzymes as eukaryotesarrow_forward
- The evolution of the highly complex eukaryotic cell was possible because.. A) Mesosomes released enzymes in to the nucleus B) Two types of prokaryotic bacteria became endo symbiotic invaders of the complex cells C) The DNA of the eukaryote cell functions within the nucleoid area D) Chloroplasts were able to use 02 to conduct photosynthesis E) the space between the two layers of the nuclear membrane contained mitochondria Explain whyarrow_forwardRNA-dependent RNA polymerase performs which of the following functions?
