Roland Piquepaille writes "German researchers at the Christian-Albrechts-Universität zu Kiel (CAU) think they've proved that genetic information can be controlled by light. The group studied the interaction between the four DNA bases — adenine (A), cytosine (C), guanine (G), and thymine (T) — by using femtosecond time-resolved fluorescence spectroscopy. The researchers think that they've demonstrated that DNA strands differ in their light sensitivity depending on their base sequences. The team thinks that it might be possible in the future to gene mutations using laser radiation. One of the project leaders said that "it might even be possible under some circumstances to make transistors from DNA that would work through the hydrogen bonds." It's not the first time I've heard about DNA computing, but this new approach looks promising. Read more for additional references and pictures of the CAU femtolaser used for this research work."

Yeah, but you can drag molecules around with lasers, so if you can detect errors, maybe you could repair them.
Of course, you'd need to increase the length of the telomeres in order to increase cell longevity, in addition to repairing the genes. It is a double problem, repairing the genes, and increasing cell lifespan. Then, you can live as long as you can before you die from violence or accident.

I first read this as "induce" or "fix", which is not accurate.

Maybe. It is a nice fantasy.
