- What is the significance of the length of a typical viral genome?arrow_forwardCompared with cells, what is unusual about viral genomes?arrow_forwardAssume you isolate a single stranded (+) RNA virus. When you examine the proteins in the virus, you find that it does NOT contain replicase enzymes within its capsid. Which of the following is true? This virus must have a gene that encodes replicase. This virus will not be able to enter a host cell. Its genome cannot be translated (the process of translation) by the host cell ribosomes. A DNA copy of the viral genome has to be made before viral genes are expressed. This virus must lack surface antigens.arrow_forward
- You are a virologist studying a newly isolated viral strain and have sequenced its genome. You find that the genome contains 25% A, 55% G, 20% C, and 10% U. Which of the following conclusions is likely correct? This is a single-stranded RNA virus This is a single-stranded DNA virus This is a double-stranded RNA virus This is a double-stranded DNA virus No conclusions can be drawn from this informationarrow_forwardAs a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate?
