Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Genetic Engineering Dna Molecules
633 wordsTwo years ago, genetically engineered bacteria, which unexpectedly killed beneficial soil fungi, escaped into sewers through human error and have become toxic to plants and survived when expected not to. 3 These are the sorts of consequences that come with playing God. DNA (deoxyribonucleic acid) - the chemical compound that makes up the genes and determines the type of proteins a cell can make - is the core of genetic engineering. It can be manipulated in ways we could never dream of such as a ...

Serotonin Reuptake Inhibitors Obsessive Compulsive Disorder
3,264 wordsBrain Chemistry and Recent Advances The mysteries surrounding the complexity of the brain and how it works has led scientists in diverse fields to search for answers. Chemicals in the brain and the reactions that take place are being understood now more than ever due to continuing research in genetics, pharmacology, and mental illness. Study and research in genetics has helped identify some of the genes involved in producing, receiving, or sending certain chemical reactions, the way they work, a...

Dna Molecules Nitrogenous Bases
1,277 wordsFrancis Crick. A name were all familiar with for his work with DNA. In keeping with the spirit of the architectonic, Crick has branched out beyond his original field of study. Crick has done some amazing work in other fields since his famous work with Watson in the 50 s. Most recently, Crick has begun to address the current hot topic in science: consciousness. Though Crick may or may not make earth-shattering observations in his book, The Astonishing Hypothesis, he at least makes a concise, coge...

Human Genome Project Dna Sequences
5,742 wordsLife as we know it is specified by genomes. Every organism possess a genome that contains the biological information needed to construct and maintain a living example of that organism. Most genomes, including those for all cellular lifeforms, are made of DNA (deoxyribonucleic acid) but a few viruses have RNA (ribonucleic acid) genomes. DNA and RNA are polymeric molecules made up of linear, unbranched chains of monomeric substances called nucleotides. Each nucleotide has three parts: a sugar, a p...
