The information in our brain is not stored in our DNA. The DNA and RNA contain information about our fenotype (the way we look or the color of our eyes). It is yet unknown if we also inherit some of the behavioral features of our ancestors, like alcoholism, smoking, homosexuality, etc. It is yet unknown if our DNA changes during our lifetime and if yes, how substantial are the changes. Anyway, it is impossible to recreate a person (with his memories, emotions and behavior) based only on it's DNA code.
The DNA nucleotides are destructible through natural chemical processes, like digestion - which is the most common. Normally, you can't recreate a pig you ate based on the genetic material in your stool. After our DNA passes through the digestive processes of worms, bateria and fungi, we are sooooo terminated!
Our counciousness, thoughts, feelings and memories are noting more than electrical currents and chemical signals. The chemical substances will be the feast of the worms and the electrial impulses will just cease to exist. Once we die and rot a little, it is impossible to be ressurected. Not even with the most advanced technology.
