Translation is:
Correct answer: A. nucleus →mRNA → ribosome
- A. nucleus →mRNA → ribosome
- B. nucleus →tRNA → ribosome
- C. nucleus →mRNA → ER
- D. nucleus →tRNA → ER
Explanation
Translation needs mRNA, which is made in the nucleus and travels through the nuclear pores to the ribosomes, where its codons are read to build a polypeptide. tRNA only brings amino acids to the ribosome and does not carry the message from the nucleus, and the ER is where some ribosomes sit rather than the reading machinery itself.

About Ribonucleic Acid (RNA)
Ribonucleic acid is generally a single-stranded nucleic acid containing ribose and uracil instead of thymine. Coverage includes mRNA, tRNA and rRNA, complementary base pairing, transcription and translation, and the differences between RNA and DNA in structure, location and biological function.
