Question

the overall purpose of transcription and translation is to:
copy dna
synthesize rna
synthesize proteins
rewatch

Explanation:

Transcription is the process of forming RNA from DNA, and translation is the process of using RNA to synthesize proteins. The overall purpose of these two processes together is to synthesize proteins. Copying DNA is the process of DNA replication. Synthesizing RNA is just one part (transcription) of the overall process to make proteins.

Answer:

Synthesize Proteins
