DNA for the 48 --- By Luka Crnkovic-Dodig DNA is used to define the way a protein is made. As you all know, a protein is a long chain of amino-acids. It is very easy to decode a DNA string and get which amino-acids are to be produced. The DNA doesn't directly initiate the construction - it must first be transcribed into mRNA (messenger RNA). The 'DNA' collection of programs is to be used for these conversions. Programs: mR2A - mRNA to Acid: Converts a mRNA string into a Amino acid chain. DNA2mRNA - Converts a DNA string into a mRNA string mRNA2DNA - Well, you guess what this does... chkDNAS - Check if the DNA/RNA string has the correct format, number of elements... It is quite easy to use. Example: What amino-acids does the following DNA string construct: "ATGATCATA" Answer: "ATGATCATA" DNA2mRNA "UACUAGUAU" mR2A "-TYR-STP-TYR" - which is the amino-acid chain. This is a pretty simple program I wrote for a friend of mine - a chem student. I myself have nothing to do with chemistry - I am just a poor CS student - so please don't blame me for any errors in this text :) cheers Luka Crnkovic-Dodig http://www.luka.home.ml.org
