DNA and Protein Synthesis Review

Transcribe the following DNA sequence into mRNA (AAG CGC TTG)

• UUC CCC AAC

• TTC GCG AAC

• UUC GCG AAC

• AAC CGC UUC

In a molecule of double-stranded DNA, the amount of Adenine present is always equal to the amount of

• cytosine
• guanine
• thymine
• uracil

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy
