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

Matthew and Bradley got into an argument. Matthew was convinced the model shown was RNA, and Bradley is positive that it was DNA. Who is right and why?

• Both of them are wrong because it is neither RNA nor DNA

• There is not enough information in the model to determine who is correct

• Matthew is right because RNA is single-stranded while DNA is double-stranded

• Bradley is right because DNA is single-stranded while RNA is double-stranded
