__ Wiki Post 3: The Process of Neuron Firing __ January,23/2014 In my life, I question everything... From why rocks form individually and not as a giant slab, to what defines a brook to a river. I question every aspect that I can think of bout nature but I have always just accepted humans and how we work. Now that this topic has been introduced to me... I mean the real basis of how we function, I have taken an interest in how our section of nature ticks. The neuron firing process is really a base system of the human body, to put it in extremely simple terms, if you touch something, neurons send the signal to your brain and your brain interprets it. but what interests me is how this process works and what our bodies can do without our help.

__ Wiki Post 2: Evolution __ Nov,20/2013 Evolution, " the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth." definition from [|Google]. I have included in this post, a video on where we came from and how the heck we managed to do it. some visual components to help your understanding and some bad web page layout because its the best i can manage to figure out. I enjoyed covering this topic although it is hard not to overlap what we covered in class. I also included some awesome sites to check out even if this is not your topic of choice.

I included this video on evoultion in my post because i liked the fast paced presentation that the presenter gives you. I found that he kept me interested throughout the video by adding little anecdotes about society and amusing comments about each evoultionary species. The information in this video was well supported with reference from Darwin's theories to modern research. The presenter also kept the information well organized by following a " family tree" animation. The video covers what problems occurred with each evolutionary species that prompted the next one, and what advantages each ones were presented with. My favorite part of the video was when he shows you how migration across the world happened and how scientists today can trace the patters using mitochondrial DNA.



__ Acquired Traits: __ Definition- -A physical characteristic that is not inherited but may be an effect of the environment or of a somatic mutation. Definition from // The Free Dictionary by Farlex- // [|http://medical-dictionary.thefreedictionary.] [|com/acquired+trait]



__ Site seeing: __ -[] This site helps to teach and understand what happens and what it means to "evolve" and I enjoyed the site as it got through to me with some foggy areas that i was having with my own understanding.

-[] This site is similar to some topics that we touched on in class but i like how it compares Lamarck's ideas to Darwin's ideas in an unbiased manner. Presenting these ideas in this way shows the brilliance, in my opinion, of these two men.

-[] This is a great site to get a basic understanding of the different species of humans, which ones were closely related opposed to others, and when the lived. Its is great because it is interactive with a good layout to deliver a nice understanding.

-[] This site is good to keep up to date with the latest news in the science world under the umbrella of evolution. it has updated headlines and theories.

__ Wiki Post 1: Genetic Mutation __ Oct,8/2013 The following wiki post is on ^ Genetic Mutation, I have included pieces on how your DNA is affected, how mutations occur, and what type of impact they have with the slightest change. I find that genetic mutation makes us think of frankenstein or some sort of horrific creation but when you strip away the un familiarities of the visual aspects of mutation and you look at the bare bones of it, really the genetic code, then it is really an interesting topic. To think that we as humans can be broken down into four words... Adnine,Thymine, Cytozine, and Gyuanine... that is something amazing. Mutations- by Bozeman Science

The above video is about Genetic Mutation (obviously) but I put it in my post because I like how it describes genetic mutation with visuals. Big and uneasy terms are not used so the video is easy to follow and understand for people without an extensive scientific background. The video talks about the genetic code and how it can be compared to a cookie recipe and it demonstrates how the product will differ greatly with even the slightest change in the most minor detail.

The below table is about the different types of mutations that are compatible to humans. It shows the type of mutation, what its classification is and how the disease is linked to mutation. for example the first description is for the red blood cell mutation picture I have to the left of this table. I decided to use this table as a picture instead of taking the information because I like how it easily displays the information and it is organized neatly and efficiently.
 * = ** Class of Mutation ** ||= **Type of Mutation** ||= **Description** ||= **Human Disease(s) Linked to This Mutation** ||
 * = Point mutation ||= Substitution ||= One base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand ||= Sickle-cell anemia ||
 * ^  ||= Insertion ||= One or more extra nucleotides are inserted into replicating DNA, often resulting in a frameshift ||= One form of beta-thalassemia ||
 * ^  ||= Deletion ||= One or more nucleotides is "skipped" during replication or otherwise excised, often resulting in a frameshift ||= Cystic fibrosis ||
 * = Chromosomal mutation ||= Inversion ||= One region of a chromosome is flipped and reinserted ||= Opitz-Kaveggia syndrome ||
 * ^  ||= [|Deletion] ||= A region of a chromosome is lost, resulting in the absence of all the genes in that area ||= Cri du chat syndrome ||
 * ^  ||= [|Duplication] ||= A region of a chromosome is repeated, resulting in an increase in dosage from the genes in that region ||= Some cancers ||
 * ^  ||= [|Translocation] ||= A region from one chromosome is aberrantly attached to another chromosome ||= One form of leukemia ||
 * = Copy number variation ||= Gene amplification ||= The number of tandem copies of a locus is increased ||= Some breast cancers ||
 * ^  ||= Expanding trinucleotide repeat ||= The normal number of repeated trinucleotide sequences is expanded ||= Fragile X syndrome, [|Huntington's disease] ||

__ Point Mutation : __

-An alteration in DNA sequence caused by a single nucleotide base change, insertion, or deletion. Definition from: from the University of Washington and the National Center for Biotechnology Information
 * Definition ** from Genetics home Reference:

-A gene mutation involving the substitution, addition, or deletion of a single nucleotide base. Definition from: by Merriam-Webster Inc.

-A point mutation is when a single base pair is altered. Point mutations can have one of three effects. First, the base substitution can be a silent mutation where the altered codon corresponds to the same amino acid. Second, the base substitution can be a missense mutation where the altered codon corresponds to a different amino acid. Or third, the base substitution can be a nonsense mutation where the altered codon corresponds to a stop sign. Definition from: from the National Human Genome Research Institute



Sites to check out- []- This site talks a little about point mutation but it also talks about the types of genetic mutations with support of visuals using the genetic code. This site also includes information on types of changes in DNA and how mutations come to be.

[]- This site includes a definition of point mutation and I really enjoyed looking through it because it has sections for different material and an easily accessible a-z glossary for specific questions.

[]- For a simple view on mutations this site provides a basic information on how mutation works by "mutating" sentences. The sites perspective is "what is mutation?".

[]- This site includes information on how mutations affect people, how the mutations occur and what it means to say that they are random, and also how the smallest mutation can have a huge effect.
