• methionine, phenylalanine, histidine, aspartate, glycine

• Methionine, proline, histidine, aspartate, glycine

• methionine, serine, histidine, aspartate, glycine

Which molecule carries the genetic code from DNA to the ribosome?

• tRNA

• rRNA

• mRNA

• DNA polymerase

Which of the following best describes the role of tRNA during translation?

How does the structure of mRNA differ from that of DNA?

• mRNA is double-stranded, while DNA is single-stranded

• mRNA contains uracil instead of thymine

• mRNA contains deoxyribose sugar

• mRNA is found only in the nucleus
