In the structure of DNA, which nucleotide always pairs with adenine?

• Cytosine

• Guanine

• Thymine

• Uracil

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

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

• Both Matthew and Bradley were wrong as this is not DNA or RNA.

• There is not enough information in the picture to conclude who was right.

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

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

Which base is found in RNA but not in DNA?

• Adenine

• Cytosine

• Thymine

• Uracil

How are DNA and RNA molecules alike?

• They are both double stranded.

• They both contain nitrogen bases.

• Their nitrogen bases always pair A - T and C - G.

• They are found in the nucleus and at the ribosomes.
