RNA vs DNA quiz

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

In eukaryotes, functional messenger RNA molecules are made from

• exons spliced together after introns are removed
• introns spliced together after eons are removed
• exons spliced together with introns
• long pieces of RNA shortened by the Dicer enzyme

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

The process of making proteins on the ribosome based on instructions from messenger RNA is called

• transcription
• transformation
• translation
• molecular biology

Changes is DNA sequences that affect genetic information are known as

• replications
• mutations
• transformations
• translations

Which of the following is NOT a pyrimidine?

• thymine

• cytosine

• uracil

• guanine
