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.
The nucleotides found in a DNA are Adenine, Guanine, Thiamine and Cytosine and in an RNA it is Adenine, Guanine, Uracil and Cytosine. Adenine always pairs with Thiamine and Cytosine pairs with Guanine in a DNA. RNA is generally single stranded but in cases where it is double stranded the same rules apply but here Adenine pairs with Uracil. The A-T and A-U bond is double bonded whereas the G-C bond is single stranded..
