Learning Goal: I’m working on a genetics discussion question and need the explanation and answer to help me learn.
In Module 5.1 we are taking a closer look into transcription and translation. This week we are going to think outside the box and explore how your (less) favorite virus does the trick. Viruses are acellular and their genome could be either RNA or DNA. To complicate things further their genome con be single stranded, double stranded, positive (+) sense or negative (-) sense. Once you select a virus, find an article or book chapter that has a picture and a description of their transcription and translation process. For the virus you select, indicate their genome, if it is single or double stranded and if it is + or – sense. Also, briefly describe if having this particular type of genome provides an advantage to viral replication. Don’t forget to comment on two other posts by your peers. I chose West Nile Virus (WNV) as it is prevalent in Arizona and it belongs to the Flaviviridae family. Other members of the family include Dengue, Yellow fever and Zika viruses. The genome of WNV is positive sense single stranded RNA (+ ssRNA). The advantage of this type of genome is that mimics mRNA (5′ to 3′) and can be translated directly into a polyprotein.
