RNA to Proteins

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

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

• nucleotide
• enzyme
• amino acid
• promoter

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

What is the term for a three-nucleotide sequence that codes for an amino acid?

• base

Which phrase best describes translation?
