Protein Synthesis Study Guide Name Per. 1. DNA is also known as the _________________________________. 2. A protein is made up of ____________________________. 3. A protein’s function is determined by its ___________ and ______________________________________. 4. Draw and label the 3 major parts of a DNA nucleotide and an RNA nucleotide. Point out their differences. DNA RNA # of strands codes for bases sugar 5. How do DNA and RNA together contribute to making a protein? Types of RNA Function 6. A DNA strand has the nucleotide sequence: ATCGAAGGTCTC. a. What will be the corresponding mRNA sequence? ____________________________ b. How many codons are present? _______ c. What will be the corresponding tRNA sequence? _____________________________ d. What part do the tRNA anticodons play in making the protein? ________________________________ ___________________________________________________________________________________ 7. What enzyme joins RNA nucleotides together? __________________________________ 8. Where is RNA synthesized? _____________________ What is this process called? ___________________ 9. Where does protein synthesis occur? ___________________ What is this called? ____________________ 10. Every mRNA triplet is called a ________, and the corresponding tRNA bases are called the ____________. 11. When nucleotide bases pair up, they are said to be _____________________________ of each other. Functions of Proteins Examples 12. Transcription takes place in the ________________________.
