Welcome to the forums Jack
lol yeah we have been talking about splicing and plasmids too in my uni lectures for Genetics. A plasmid is an extra piece of chromosomal DNA, cabable of replication and able to be transferred, normally found in bacteria as circular DNA but do not encode genes. How its used to create more DNA gets into talking about gene cloning, using them as vectors etc.
Splicing we talked about quite recently. Its removing sections from a strand of mRNA (called introns) which do not encode genes to leave only the exons (which do encode genes) in the strand. They are 'spliced' out and are not present in the mature strand of mRNA (complementary copy strand from the DNA template)
In the game of course plasmids are a completely different thing and splicing is just taking too much ADAM causing them to go insane, deform etc. Dont know if you were actually asking for an explanation to what those actually were but i gave it anyway lol. I enjoy Genetics, shame it can be really confusing and quite difficult at times (hope i have done ok in my exam)..
