Bell Work • Pick up the task card review sheet • Turn in your hippogriff protein synthesis • Get out your web quest and notes REMINDER: Test Tomorrow over DNA, RNA and Protein Synthesis
Nucleotide Card #1 Identify each part of the nucleotide above: • What is the circle? • What is the pentagon? • What is the rectangle?
Card #2 What is the difference between a purine and a pyrimidine? Which bases belong in each category?
Card #3 How do the bases in DNA pair? How many hydrogen bonds are found between each base pair?
Card #4 What are the three biggest differences between RNA and DNA?
Card #5 Label each type of RNA and list the function of each.
Card #6 What are the two stages of protein synthesis and what is produced in each?
Card #7 What is the correct sequence for the transfer of information?
Card #8 What is the enzyme that completes transcription and what two jobs does it do?
Card #9 What is the start codon? What will be the first amino acid added to every protein?
Card #10 Identify each labeled component on Figure 1.1
Card #11 Translate the following mRNA: CUC – AAG - UGA
Card #12 Create an mRNA sequence that could code for: His – Glu - Pro
Card #13 During which stage of protein synthesis will you find ALL THREE types of RNA working together?
Card #14 What mechanism GUARANTEES that the tRNA adds the correct amino acid in the order specified on the mRNA?
Answer Key: • Check your answers against the key to ensure you are studying the correct information
Nucleotide Card #1 Phosphate Nitrogen Base Deoxyribose - Sugar
Card #2 • Pyrimidines = one ring in the base structure • Thymine and Cytosine • Purines = two rings in the base structure • Adenine and Guanine
Card #3 ADENINE THYMINE GUANINE CYTOSINE Guanine pairs with Cytosine and they have 3 hydrogen bonds Adenine pairs with Thymine and they have 2 hydrogen bonds
Card #4 DNA = Deoxyribose Sugar, Double Stranded and Thymine RNA = Ribose Sugar, Single Stranded and Uracil
Card #5 mRNA = copies the DNA code and carries it to the ribosome rRNA = makes the ribosome tRNA = carries amino acids to the ribosome and links them into a polypeptide chain according to the code on mRNA
Card #6 Transcription = mRNA Translation = protein
Card #7 DNA – RNA – PROTEIN
Card #8 RNA Polymerase = unzips DNA and copies the code to create mRNA
Card #9 AUG = MET
Card #10 A = NUCLEUS B = MRNA C = RIBOSOME D = TRNA E = ANTI-CODON F = CODON G = MRNA
Card #11 Translate the following mRNA: CUC – AAG – UGA LEU – LYS - STOP
Card #12 Create an mRNA sequence that could code for: His – Glu – Pro CAU OR CAC GAA OR GAG CCU, CCA, CCG, CCC
Card #13 During which stage of protein synthesis will you find ALL THREE types of RNA working together? TRANSLATION
Card #14 What mechanism GUARANTEES that the tRNA adds the correct amino acid in the order specified on the mRNA? The interaction between tRNA anti-codons and the mRNA codons – an anti-codon can only bind ONE mRNA codon
