DNA, RNA and Protein Synthesis

Why is DNA important?

• it is very small and very complicated

• it's in everything

• it serves as the blueprint (instructions or recipe) for the traits of all living things

• because we eat it every day for energy

How does RNA differ from DNA?

• RNA contains uracil and deoxyribose
• RNA contains ribose and thymine
• RNA contains uracil and ribose
• RNA contains adenine and ribose

How would the DNA sequence GCTATA be transcribed to mRNA?

• GCUAUA
• CGATAT
• CGAUAU
• GCUTUT
