Anatomy Shared Article Research

This blog exists for the Anatomy students at Tree of Life Christian School. We will be reading various scientific articles, summarizing our research, and then commenting on others' summaries. We hope to broaden our view of the current research surrounding the human body, and to help others see how truly amazing the design of the human body is.

A Whole New World...again

http://www.sciencenews.org/articles/20070908/bob9.asp

The idea of the gene is being questioned. It was firmly set in the “central dogma” but now, fifty years later, it is changing a great deal. It used to be believed that there was only a very small part of the genome that actually did anything at all. Now it is being discovered that all the other parts of the genome is useful.
This “other part” is what scientists call “junk DNA”. This is made of mostly RNA. Until very recently RNA was second fiddle to DNA. But studies are now showing it does much more than assist the DNA. RNA is being shown to regulate protein as well as make it. New types of RNA are constantly being discovered.
All this information, which has just been discovered, took a huge effort to find. It took 35 teams of scientists from all over the world four years to code one percent of the human genome. They collected over six hundred billion data points. This project was called ENCODE.
All this new information is being discovered, and it is reforming older theories. It was believed that there were over one hundred thousand human genes. When ENCODE published their results it was seen that there was only about twenty-three thousand human genes, not much more that a round worm who has only twenty-one thousand genes. Scientists say that what makes the human body more complex and even contributes to our brain formation is junk DNA.
The huge amounts of RNA that perform many of the genomes vital jobs are key in the development of complexity. Along with this idea, many diseases such as diabetes and even cancer are being linked to mutations in junk DNA. Or at least what scientist think are mutations in the RNA. With there being so many new advances in the idea of the gene, the effects of a single mutation are hard to predict because there can be so many and they can be scattered so widely.
The new studies being done and the studies that have already produced results have shattered the previously accepted idea of the gene. They are rebuilding it slowly and the out of focus picture of a genome is being refocused, at least for now.

I think this article just makes it so clear that evolution is false. It talks about how making all this junk DNA would be against nature if it had no function. This article also just makes me think about how awesome God is. All this stuff we study that we know so much about is just a small part of this huge idea. God created all this, each with a very specific purpose and we have barely scratched the surface. And we don’t even know if we are right. God created everything to have a purpose and everything is so intricately and delicately designed that no matter what we think, God knows how important it is.

The discovery that "junk RNA" really has a purpose is almost odd. Of course there is a purpose. Our body has been designed for a reason. Why would a designer design something useless? Hopefully scientist really think about what this finding shows. Nothing in a human body is purely junk.

I agree with the previous comment that nothing in the body is junk. I think this article just shows how far we have to go in the field of understanding the human body. We thought we knew it all and we come to learn that we were pretty much completely wrong.

God continually amazes me by His creation. Our bodies are unbelievably complex and no matter how hard we try I don't believe that we will ever figure ourselves out. It was interesting that scientists thought that they had it figured out only to see that they had been wrong the last fifty years.
