What type of RNA acts like a delivery truck, delivers amino acids to the ribosome for protein synthesis, and then leaves empty again, to go collect another amino acid?

• Transfer RNA

• Messenger RNA

• Ribosomal RNA

• Mitochondrial RNA

DNA codes the information necessary to produce the proteins needed by the body. To make these proteins, DNA first undergoes a process known as transcription. This is when the information on a DNA strand is transferred to a molecule very similar to DNA, known as ____.

• Nucleotides

• Amino Acids

• RNA

• Ribosomes

Translation and protein synthesis are taking place at the ribosome in this model. Where did the original instructions for this process originate?

• RNA in nucleus

• DNA in nucleus

• tRNA in cytoplasm

• mRNA attached to ribosome
