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.

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.

DNA is the heredity material which passes on from the parents to the child, for the child to inherit some traits from the parents.

mRNA (messenger RNA) carries the codes of instructions for protein synthesis from the DNA in the nucleus to the ribosome.

There are also other RNA like the rRNA (ribosomal RNA) which has no known function yet, and the tRNA (transfer RNA) brings the amino acids to the ribosome in the correct order so that they can built into the new protein.

Also (for more information), your RNA comes form your DNA. And the process involved is the RNA transcription.

Hope it helps!

dna is the storage form of cellular information. it is more stable than rna for chemical reasons. however, it is like a complete instruction manual, containing (almost) all the information necessary for making an organism. the cell, however, only needs the instructions for itself, or its own cell type. the mrnas are the specific instructions copied off the dna, but the cell only copies (or transcribes) the ones that it needs. the 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, and only the ones that are useful to that particular cell are copied.

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.
