RNA/Protein Synthesis/Mutations

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

The process by which the genetic code of DNA is copied to mRNA is called

• translation

• transcription

• transformation

• replication
