A type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate.
Hear the fascinating story of how retroviruses were found and proven against the vast majority of scientific opinions that deemed the idea to have been nonsense for many years! This is like science-fiction of the nasty kind, found in this Revisionist History podcast episode below!
To best understand this post, you might need a little anthropology background on human prehistory (before written history) if you don’t already know it well. The award winning set of videos below are about as good, simple and complete a picture on human evolution as I’ve ever seen. If you have the time, I would highly recommend you watch them because I think this knowledge of our past is interesting and beneficial to help us all better understand how we came to be who we are today. I’ll refrain from taking shots at Creationists who are being phased out by evolution as people get more aware and intelligent. 😉
Last week, I began a new adventure in life by sending in a saliva sample for DNA genotyping with a project and company called 23 and Me at 23andme.com. In layman’s term, genotyping is like a high level, or crude, DNA testing on focused on certain critical parts that make up a tiny part of the entire human DNA. From 23 and Me, I will get some health and ancestry information, from likelihood of disease contraction to drug and food reactions to family and race heritage. There will also be lots of other interesting facts like whether you’re genetically predisposed to liking cilantro. 🙂 Continue reading →
