All about DNA (Deoxyribonucleic acid)
FACTS: Deoxyribonucleic acid, or DNA, is the amazing molecular double helix that contains the genetic codes for all known life. First identified in 1869 and accurately described in 1953, its very existence provides a new understanding about how life works.
The two spiraling strands that coil around each other are comprised of sugar and phosphate molecules which provide support for the code- carrying rows of base pairs. The four bases – adenine,(A), thymine,(T), guanine,(G), and cytosine,(C) – always have a matched pair, A’s with T’s, G’s with C’s. As a result, the 4 letter code is effectively duplicated, greatly enhancing its stability and allowing for efficient replication.
And what can you spell with this 4 letter alphabet? A series of 3 letter words which specify the 20 amino acids needed to make all of the proteins necessary for life.
The human genome contains about 3 billion letters (bases), or a billion words (codons). These words, collected in 23 chromosomes, describe the more than 20,000 genes that are the substance of our bodies. Some genes take a few hundred words to describe, some take hundreds of thousands.
99% of the DNA in every individual is identical – and indeed, much of our DNA is shared with every living creature on Earth.
But the tiny variations in the words are sufficient to fashion the great diversity of creatures on the planet, and the uniqueness of every human being that has ever lived.
|Name||The name describes the molecule’s chemical structure consisting of a sugar, phosphate, and base.|
|Actual Size||The entire human genome contains is made up of about 20 thousand genes. That’s over 3 billion nucleotide bases. Unwrapping all the DNA in a human body is enough to reach the moon 6000 times!|
|Where It Lives||DNA stands for Deoxyribonucleic acid. It’s the genetic material and basis of life for nearly all living organisms, made of chemical building blocks called nucleotides. The nucleotides are cross-linked into double-stranded chains and packaged neatly into chromosomes. Nucleotide bases form sequences called genes, which code for proteins. |
|History||This genetic material was first discovered in 1869 by Friedrich Meischer. Nearly a century later, in the early 1950’s, James Watson and Francis Crick to discovered its double-helix structure.|
|Fascinating Facts||The Human Genome Project was an international collaboration to sequence and map the entire human genome. In February 2001, the International Human Genome Sequencing Consortium published the first draft of the human genome.|
