Transcription and Translation Practice KEY 2026/2027 (6pages)

DNA vs. RNA In the spaces provided, write “D” if the statement is true of DNA. Write “R” if the statement is true of RNA. Write “B” is the statement is true of both DNA and RNA. ______1. consists of a single strand of nucleotides ______2. made of nucleotides linked together ______3. contains deoxyribose ______4. contains the nitrogen base Uracil ______5. contains ribose ______6. is a nucleic acid ______7. consists of a double strand of nucleotides ______8. contains a base that pairs with adenine Complete the table below DNA mRNA tRNA Number of strands 2 1 1 Location Nucleus Nucleus to cytoplasm cytoplasm Components of nucleotide Deoxyribose, phosphate, nitrogenous base (G,A,T,C) Ribose, phosphate, nitrogenous base (G,A,U,C) Ribose, phosphate, nitrogenous base (G,A,U,C) Function Stores genetic information that codes for all proteins made in the cell Carries temporary copies of the message contained in DNA to the ribosome to be translated Carry amino acids to the ribosome to create the proper proteins R B D R R B D B This study source was downloaded by 100000850872992 from CourseHero.com on 02-17-2026 12:52:28 GMT -06:00 https://www.coursehero.com/file/133386374/Transcription-and-Translation-Review-Guide-2026-SOLUTIONS-1docx/ Structure (drawing) Match the properties in column A, with the nucleic acids in column B Column A ______9. carries amino acids to ribosomes ______10. composed of two chains of nucleotides ______11. contains Thymine ______12. contains ribose ______13. involved in translation ______14. made during transcription ______15. contains phosphate & ribose ______16. contains Cytosine ______17. contains Uracil Transcription Use the word bank below to label the diagram of transcription: B Column B A.
