Solution

The correct option is A (A) and (C)
During translation, messenger RNA (mRNA) provides the template to synthesize a chain of amino acids that form a protein. Transfer RNA (tRNA) reads the genetic code and brings amino acid specified by the codon. RNA polymerase binds to DNA sequence called the promoter and initiates transcription. A segment of DNA coding for the polypeptide is called as the exon. Non-coding DNA segment is called the intron. Thus, the correct answer is option A.
