DNA RNA -Helps with protein synthesis by mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). -Stores genetic information. -Maintains growth and repair. -Controls all cellular activities. -Contains protein codes. -Ensures each daughter cell & gamete receives exact genetic information.
