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 double stranded, so 2. RNA is single stranded, so 1. DNA is located in the nucleus. RNA is located in a few places because there are different types of RNA....RNA is copied in the nucleus (mRNA), and then shipped out to a ribosome (which has rRNA and tRNA), floating in the cytoplasm. DNA has 2 strands, RNA just 1, and they both can be found in the nucleus of the cell.
