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 & Proteins. DNA & RNA is made of Nucleotide which are our genetic material in which we are coded.Our Structure and Functions are done by protein, which are build of Amino acids
Here in this we try to manipulate DNA, RNA, Protein strings using Biostring Package
Install Packages
Biostrings
