Question

Quizplus · Accepted Answer

Transcription occurs within the nucleus where DNA is transcribed into mRNA, which is then transported to the cytoplasm for translation. Translation occurs on ribosomes in the cytoplasm where the mRNA is translated into a polypeptide chain. A is incorrect because amino acids are the building blocks of proteins, not DNA. C is incorrect because uracil is present in RNA in place of thymine, not DNA.
