slide2. Genomic Sequences DNA and RNA can be represented practically by a very long sequence comprising of three identical letters, A (adenine), G (guanine), and T (thymine). The fourth letter in DNA is C (cytosine) while in RNA it is uracil (U). There are two complementary strands of DNA which are called base-pairs. The other type of genomic sequences is protein which can be represented by a sequence of over twenty symbols (A, C, D, E, F, G, H, I, K, L, M, N, P, Q, R, S, T, V, W, Y). These symbols are transcriptions of selected DNA stretches.
The following is the example of a DNA sequence in FASTA format taken from MGRC, (2008):<br>
