DNA is the master code of the cell.
It holds all the genetic information for the cell or the organism.
DNA with a collection of host of protiens program the mRNA so the chemical messenager or protien will be created for the need material thus the messenager.

Wow, you got a lot of complicated answers. Did you understand any of them? Neither did I.
You asked for function.
The DNA of a cell contains all the information that the cell needs to run itself properly. The DNA communicates with the rest of the cell via the mRNA. The mRNA tells the cell what to so according to what the DNA dictates should be done.

the genome is like a complete instruction manual for making an entire organism, and that information is stored in dna. a cell, however, only needs a subset of instructions for itself at any given time, and different cells use different instructions. mrnas are the individual instructions copied off the dna, and the cell only copies (or transcribes) the ones that it needs. these mrna instructions are then translated into protein molecules, which do things like move your muscles or help you see. this is called the central dogma of molecular biology : dna -> rna -> protein. the mrna is the intermediary between the dna and the protein, where the dna stores the information and the protein does the work.

DNA (deoxyribonucleic acid) is the main form of genetic material present in organisms. In most eukaryotic organisms, it is present in the nucleus of cells and directs all the activites of the cell. During transcription, DNA is converted to mRNA (messenger ribonucleic acid). mRNA is the form of DNA that can leave the nucleus (because it is small enough to fit through the nuclear pores of the nuclear envelope). when mRNA is present in the cytoplasm, two subunits assemble on the mRNA to form a ribosome, ready to translate it into a polypeptide chain consisting of many amino acids (the primary structure of a protein).

DNA contains the genes which are the codes for making proteins.
mRNA is formed as a complementary copy of a gene in DNA. mRNA takes this information to a ribosome where tRNA brings amino acids according to the pattern of codons in the mRNA.
