When Genes Go Retro

The article discusses what goes on with DNA and RNA. It discusses how DNA holds the information, but RNA does all the work. It takes it in an interesting way thought. It talks of DNA being the celebrity just sitting and looking pretty, while RNA does all the work in the cell. It then goes to talk about retrogenes. They are genes that are made from going backwards when making the DNA. They are like DNA but do no have to stay with the "parent" DNA and can have different funtions. The retrogene can be turned on or off in gene expression. It ends in telling how it effects the sex X and Y chromosomes in humans.
I'm not really sure why this is in an opinion section. It mainly just tells about genes and retrogenes. But it was an interesting topic and the author was very good at keeping attention. She knew the facts but did not present them in a boring way. She used common language that everyone could understand. She also seems credible because she cites her sources at the end of the article. Overall effective article with getting her information across, but I'm not sure where the opinion comes in.
