Connecticare is a great place to work. It is a smaller company that provides a large variety of work during your day, week or month. I never get bored and there is always more work to do which allows for strong job security.
The simple summary is that DNA makes RNA, and then RNA makes proteins. DNA, RNA and proteins all consist of a repeating structure of related building blocks (nucleotides in the case of DNA and RNA, amino acids in the case of proteins). In general, they are all unbranched polymers, and so can be represented in the form of a string.
DNA is found in the chromosomes of the nucleus in a cell and it carries hereditary information. RNA is located in the cell but not in the nucleus. Just as proteins consist of long chains of amino acids, DNA and RNA consists of nucleic acid chains called nucleotides. Nucleotides are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil. They are abbreviated (A, C, G, T, U).
