• Thymine

• Guanine

• Uracil

What is the main structural difference between DNA and RNA as depicted in the image?

• DNA has one strand while RNA has two strands.

• DNA contains uracil while RNA contains thymine.

• DNA has a double helix structure while RNA has a single helix structure.

• DNA is made of ribonucleic acid while RNA is made of deoxyribonucleic acid.

What is the function of DNA?

• To transport genetic information out of the nucleus

• To store all of our genetic information within the nucleus

• To produce proteins in the cytoplasm

• To provide energy for cellular processes

What role does RNA play in the cell?

• It stores genetic information within the nucleus

• It assists in the replication of DNA

• It is used to transport pieces of the genetic information out of the nucleus so proteins can be made in the cytoplasm

• It forms the cell membrane
