Talk:Point mutation (view source)

Philip, I have to ask about this addition, point mutations do not add information to the genome. Whereas they do not change the genome size they can change what is actually produced. For example, the sentence "I love my cat" vs. "I love my hat". Both are of the same size however the information is different. While this was a simple explanation it does apply to genomic expression. Many proteins are duplicated on the genome, this actually allows for gene regulation. Based on the promoters and regulatory proteins it is possible to have a point mutation in one of the duplicated sequences that changes the function of the protein expressed, thereby increasing the information (original protein and mutant now expressed) but not changing genomic size. Unless you are equating genomic size with information. It might help if I write about gene regulation sometime, most are not exposed to it in college since it is a very specific topic.--[[User:Able806|Able806]] 09:33, 4 February 2009 (EST)

:: Rather a late response, and pointless, given the merge, but I was primarily correcting the wording to what the reference was actually claiming. [[User:Philip J. Rayment|Philip J. Rayment]] 09:41, 11 February 2009 (EST)

:::Thank you, I had guessed that after reading through the reference a bit. Something I have to ask, the papers published by the ICR and such groups, are they available for scientific review? I would like to research their position about genetic information particularly in relation to increase of information. From what I know of molecular genetics and information molecules, the ability for information to be increased through mutation is possible and has been observed. I would like to research the claims of ICR and such as to why they believe these examples fail. If you could be of assistance with this I would greatly appreciate it.--[[User:Able806|Able806]] 10:33, 11 February 2009 (EST)
:Can you write some simple introductory material about the [[genome]], [[genome expression]], [[regulatory protein]]s, [[gene regulation]], and [[mutation]]? Nearly all of our readers need to know about the basics before they can learn about advanced topics such as [[point mutation]]. --[[User:Ed Poor|Ed Poor]] <sup>[[User talk:Ed Poor|Talk]]</sup> 09:39, 4 February 2009 (EST)
