More likely RNA or some other protein. The oft-mocked Lamarckian concept, of genetic learning (not just natural selection) is probably real, and some reverse transcription does happen, namely that DNA is edited within the life of one organism. But remembering where you left your glasses is probably handled at a lower level than editing your chromosones. We do have short-term memory too. We don't want to junk up our chromosones remembering every grocery list.
