Question

why is dna considered to be the code of life?○ it is unique to each species.○ it is present in all living cells○ it is responsible for the origin of life.○ it contains information to form proteins.

Explanation:

DNA acts as the "code of life" because its nucleotide sequence encodes the instructions for synthesizing proteins, which carry out nearly all critical biological functions in organisms. The other options are incorrect: while DNA is unique to species and present in most living cells, these do not define its role as a genetic code; additionally, DNA is not responsible for the origin of life itself.

Answer:

It contains information to form proteins.
