Human Cloning (Geek-Alert)
So I was sitting at a night-club with some friends this evening discussing literature while the Burlesque performers were practicing getting their pasties gyrating in unison back stage.
Both my friend and I had read all of Heinlein's Lazarus Long stories, however his girl-friend had never heard of them. We covered some of the back-plot including ( Read more... )

Chemical DNA Change: A process called DNA Methylation chemically modifies the Cytosine (the C in the G-C / A-T base-pairs). Methylation of a genes Cytosine can prevent the gene from functioning by blocking it's transcription. This chemical change is persistent across cell division - see Epigenetic Inheritance.
DNA Methylation is reversed in a process surprisingly called Demethylation. This process occurs in the development of spermatozoa prior to fertilization and the formation of the zygote.
Structural DNA Change: Histone buildup around a genes DNA results in the DNA becoming tightly bound. This tight binding limits the genes functioning by restricting its transcription. This binding is persistent across cell division - see Epigenetic Inheritance.
Histone binding appears to be present in the spermatozoa and in the zygote, however the spermatozoa histone appears to be 'cleaned' before the first round of cell-replication.
Turkey Baster: I'm certain there are more pleasurable applicators than the turkey baster!
