In biology, a mutation is a permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from damage to DNA which is not repaired, errors in the process of replication, or from the insertion or deletion of segments of DNA by mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity.
Mutation can result in many different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. Mutations can also occur in nongenic regions. One study on genetic variations between different species of Drosophila suggests that, if a mutation changes a protein produced by a gene, the result is likely to be harmful, with an estimated 70 percent of amino acid polymorphisms that have damaging effects, and the remainder being either neutral or marginally beneficial. Due to the damaging effects that mutations can have on genes, organisms have mechanisms such as DNA repair to prevent or correct mutations by reverting the mutated sequence back to its original state.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Most Shocking is an American reality television show produced by Nash Entertainment and truTV Original Productions. It generally features narrated video of criminal behavior, police pursuits, robberies, and freak accidents. It also airs a spinoff series Top 20 Countdown: Most Shocking which began airing on October 3, 2009.
The program held a TV-14 rating due to extremely violent situations depicted in the videos. The series currently reruns on The Justice Network as of October 26, 2015.
Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes in the recipe can result in changes in the food. He describes the three major point mutations; substitutions, deletions and insertions. He also describes several chromosomal mutations.

The human body is a very strange, and complex thing. One change in DNA and a body can completely change. Subscribe to Talltanic http://goo.gl/wgfvrr #10 - The Claw The lobster claw hand is a mutation where an individual’s hand or foot has a cleft where the middle finger or toe should be. These split-hand and split-foot deformities are also sometimes associated with hearing loss. Thankfully, there are surgical procedures that can correct most of these malformations. #9 - SCID SCID or Severe Combined Immunodeficiency Disorder is also known as the Boy in the Bubble Disease. This disorder is when the person is born without an effective immune system. The idea behind the bubble is that it was an isolated space that was free from unfiltered air and life-threatening pathogens that would qui...

They say freedom
Comes to those with every hair in place
On the edge of extinction
It flickers across your face
In the mirror in the morning
When your life line begins to speak
When you hesitate and blunder
When your smile and grit your teeth
They say that's when
To the world I will declare
We will fly like truth through a needles eye
To pay the price of freedom
To pay the price of freedom
Your fear of loneliness
I watched it wall (?) you in
You took the line of least resistance
And you let your jailor win
You got to light your way out
Or you will never escape
Reach out and take it
Before it's too late
You say that's when
To the world I will declare
We will fly like truth through a needles eye
To pay the price of freedom
To pay the price of freedom
Lost in space in the second hand rides
Hands full of bottles and plastic bags
Hungry for money, hungry for love
Waiting for the manna from the heavens above
Yeh only the rich can afford to be unfaithful
Hey only the rich can sin and keep it tasteful
But I swear
To the world I will declare
We will fly like truth through a needles eye
To pay the price of freedom
We will fly like truth through a needles eye
To pay the price of freedom
To pay the price of freedom
