Give me objectives answer on his DNA

Specifically, DNA's objectives include:

1. Storing Genetic Information: DNA sequences encode the information for proteins and functional RNA molecules, which carry out most of the work in cells.
2. Replication: DNA must be accurately copied so that genetic information can be passed from one generation to the next during cell division.
3. Expression of Genetic Information: The information stored in DNA is transcribed into RNA, which is then translated into proteins. This process allows cells to build and maintain themselves.
4. Mutation and Evolution: While accurate replication is key, occasional changes (mutations) in DNA are also essential for genetic variation, which drives evolution.
