For those with no experience I have provided three sequences: (a) a DNA sequence, (b) a protein sequence, and (c) four protein sequences presented in FASTA format. The availability of online tools permits even the novice molecular biologist the opportunity to derive a considerable amount of useful nformation from nucleotide or protein sequence data. Analysis of nucleotide and protein sequence data was initially restricted to those with access to complicated mainframe or expensive desktop computer programs (for example PC/GENE, Lasergene, MacVector, Accelrys etc.).
