DNA is associated with proteins mainly for two reasons:

  1. for catalytic action,
  2. for packaging.

Explanation:

During replication and transcription, several enzymes act on DNA. These enzymes (chemically proteins) mostly remain associated with DNA.

DNA is acidic, thus basic protein histamin get associated easily with DNA. Histone helps in tight packaging of DNA to form chromatin.
