AI Thread Summary
The discussion centers on the role of the tobacco mosaic virus in genetically modified organisms (GMOs). It is highlighted that the virus serves as a vector to deliver genetic information to plants, enabling the expression of desired genes. However, there is a clarification that the mosaic virus does not carry plasmids; this function is attributed to Agrobacterium tumefaciens and its Ti-plasmid. The tobacco mosaic virus can have sections of its RNA genome replaced with various sequences for functions such as tagging proteins or silencing gene expression through siRNA. This underscores the virus's utility in plant genetic engineering.

What roll does the mosaic virus play in GMOD food?
 
Biology news on Phys.org
Tobacco mosaic virus is used to deliver genetic information to plants. I believe that the genetic information is in the form of a plasmid.

It is my understanding that the mosaic virus is used to turn 'on' genes that a GMODer wishes to express. How does this happen?

Ouch, viruses do not carry plasmids. You are confusing it with Agrobacterium tumefacies, an alpha-proteobacterium and its Ti-plasmid.
A virus itself is a vector. Certain areas of the viral (RNA-)genome can be replaced with other sequences with a variety of function. This may include, but not be limited to fluorescent proteins for visualization and tagging or to use it as siRNA to shut down protein expression.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
