Genetic Information
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.--Able806 09:33, 4 February 2009 (EST)
- Can you write some simple introductory material about the genome, genome expression, regulatory proteins, 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. --Ed Poor Talk 09:39, 4 February 2009 (EST)
