Chemistry Week 6 – The Cell

The human cell is a very complex organism, of which there are trillions within the human body. The interior of a cell is lined with what is called the cell membrane. Surrounded by a membrane in the center of the cell is the nucleus, which contains the chromosome. Inside the chromosome is deoxyribonucleic acid, or, DNA. The blueprints for the cell are comprised of the DNA and an organelle inside the cell called a mitochondrion.

As the DNA never leaves the nucleus, the blueprints are duplicated. These duplicates are called ribonucleic acid, or RNA. This is simply a transcription of part of the DNA into a form in which it can travel as a messenger to the proper ribosomes in the body. This type of RNA is called Messenger RNA, or mRNA. RNA is also used to select the correct amino acid for each ribosome in order to create new proteins in the body. These are called Transfer RNA, or tRNA.

The interior of a cell is a very crowded place. A certain type of cell called an Escherichia coli, which is just one five-hundred-thousandth of a meter in length and two-millionths of a meter in diameter, can hold nearly 4,300 different types of proteins. This crowding is beneficial in a lot of ways; for example, the strength of interactions between cells because of the interior crowding is believed to be of key importance in such processes as DNA transcription.

Did God Create life? Ask A Protein

Today I read an article by this same name on creation.com, discussing the various aspects of proteins that prove the existence of an intelligent Creator. I highly recommend this article, especially to those of you who are atheists.

One of several aspects of proteins that is described in the article is the folding of proteins. In order to function properly, each protein must fold itself into the exact right shape to fit in its position, similarly to the way keys work. This must be done countless times per day inside the human body. How does it fold by itself? With the help of specialized proteins called chaperones. These are in charge of assisting the other proteins in folding and in finding their way towards the one spot where they will fit in a vast spectrum of places they might travel if unassisted. These too have chaperones to fold and direct them, which eventually begs the question, how was the original chaperone created and directed?

This is impossible to answer if there is no intelligent Creator behind it. You cannot tell me a random huge explosion billions of years ago followed by millions of years of evolution could have developed such an intricate system for human life. There lies the argument that Charles Darwin, the well-known 19th century author of On the Origin of Species who created the theory of evolution was a scientist who put in a lot of research to come to his conclusion about how life began. This argument is not invalid. But his theory is impossible based on the evidence found through modern discoveries like DNA and the intricacies of the human body.

Think for a moment. How foolish is it to believe that all this came from random fluctuation of the universe that perfectly designed life and it’s most complex aspects? The only reasonable conclusion is that an all-knowing, all-powerful Creator as described in the book of Genesis is behind it. Thank you for reading.
