you isolate a virus and discover that it contains a single-stranded (ss) RNA genome. How would you determine if the virus has a + sense of a - sense ssRNA genome?
Homework Answers
By sequencing of RNA extracted from isolated virus
- If the isolated RNA contains the cis functional elementary sequences like UTRs, shine dalgarno sequences, star codon, stop codon etc. in preferred direction on that isolated strand then that would be the (+) sense ssRNA
- If those sequences are present as complementary sequence from the sequence of isolated RNA then that would be the (-) sense ssRNA
Because (+) sense RNA can be translated but for (-) sense RNA, it has to be converted into (+) sense RNA, then it will be translated.

COVID 19 is a positive sense single stranded RNA virus. Which of the following is the case, given this information? It integrates its RNA into a host cell this group of viruses is not generally known to infect humans It requires viral reverse transcriptase to convert its genome into a positive sense RNA strand it has a double stranded genome the genome does not need to be transcribed in order for viral proteins to be produced

Influenza and polio are both caused by single-stranded RNA viruses. The influenza virus particles contain the enzyme RNA polymerase whereas poliovirus does not. What accounts for this difference?

1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...

The influenza virus contains an RNA genome. Scientists typically need to make a new flu vaccine every year because Multiple Choice the common influenza virus can come from many species of animals including cats and dogs. people change their habits each year and become susceptible to different strains of the virus. the virus develops resistance to the vaccine. our bodies develop resistance to the vaccine and it becomes less effective. the virus can mutate into new strains.

Sometimes a single-stranded molecule of RNA is able to fold back on itself because the nucleotide sequence on one part of the RNA is complementary to another part. This sequence motif directly results in a: Group of answer choices transcription factor binding site RNA polymerase hairpin-shaped structure membrane protein A large number of new mutations occuring in an animal genome every generation would be acceptable if: Group of answer choices there were good DNA repair mechanisms most of the genome...
