Understanding DNA and RNA

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

The process by which the genetic code of DNA is copied into a strand of RNA is called

• translation
• transcription
• transformation
• replication

Which of the following describes RNA?

• RNA is usually double-stranded and contains the base thymine
• RNA is usually single-stranded and contains the base uracil
• RNA is longer than DNA and uses five bases to encode information
• RNA is made in the nucleus of eukaryotic cells and stays there to carry out its functions

In messenger RNA, each codon specifies a particular
