Question

transcription and translation
what is the end result of translation?
it produces a duplicate copy of messenger rna
it produces a duplicate copy of original dna
it forms a polypeptide
it forms ribosomal rna

Explanation:

Translation is the process in which the sequence of codons in mRNA is used to synthesize a polypeptide chain. mRNA is decoded by ribosomes, and tRNA brings amino acids that are linked together to form a polypeptide. Producing a duplicate copy of mRNA is not translation (that's related to other RNA - related processes like some RNA replication in viruses). Producing a duplicate copy of DNA is DNA replication. Forming ribosomal RNA (rRNA) is transcription and processing of rRNA genes.

Answer:

It forms a polypeptide
