Genome system

On September 6th, 2010 we had a female speaker come in and speak amongst us about genomes. This had to be the most exciting lecture in the whole course beside Dr. Alton B. Pollard lecture with the Jadakiss video. Both of these lectures were my favorite. While most people felt that the genome lecture was incredibility boring I found it beyond interesting. I love science and always will and that’s probably why I’m a chemistry major.
I already knew everything she was speaking on so it made it easier to take notes on my mbongi form and follow along. She explained to us that a DNA molecule consists of two strands that wrap around each other to resemble a twisted ladder whose sides, made of sugar and phosphate molecules. The DNA molecule is most commonly known as the double helix. The strands are connected by rings of nitrogen containing chemicals that our known as bases. There are 4 different bases that are present in DNA which are Adenine, Thymine, Cytosine, and Guanine. These bases are always paired where Adenine connects to Thymine, and Cytosine connects to Guanine. These pairings produce 4 different base pair possibilities—A to T, T to A, G to C, and C to G. This sequence is grouped into 23 distinct parts known as chromosome pairs. Science proves that the human genome is the latest in a long line of evolution, which can and is usually considered, by many, to be the architectural blueprint for human life.
