Which blood vessels carry blood away from the heart?
i thought it was arteries, and i checked on the internet and the websites also say it is arteries but the answer in the book says veins. i have checked and re-checked that i haven read it properly and it says veins so could it be possible that the book has a mistake. it is the aqa biology revision guide or have i just completely misunderstood the question or the whole explain for reading my confused thoughts

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.
