The main function of tRNA is to...

• carry a message that, when translated, forms proteins
• form a portion of ribosomes
• string together complementary RNA and DNA strands
• bring amino acids from the cytoplasm to the ribosomes

• Cys-His-Leu-Asn-Stop

• Thre-Val-Glu-Leu-Iso

• None of the above

Once the DNA is copied into RNA, it goes to what organelle to begin protein synthesis?

• nucleus

• rIbosome

• cytoplasm

• centriole
