Bioinformatics is an amalgamation Biology and Computer science.Biological Data is manipulated using Computers and Computer software’s in Bioinformatics. Biological Data includes DNA; RNA & Protiens. DNA & RNA is made of Nucleotides which are our genetic material in which we are coded.Our Structure and Functions are done by protein, which are build of Amino acids

In the exercises below we cover how we can Manipulate Biological Data using Biostrings package in Bioconductor.
