The flashcards below were created by user ChapinJeanie on FreezingBlue Flashcards. What would you like to do?


  1. Gene
    • Segment of DNA coding for 1RNA
    • transcribe code into RNA which then goes to the cytoplasm
  2. Codon (triplet)
    • specifies the placement of a single amino acid
    • needs to be a set of 3
    • A-A-A-(A-U-G)-C-C-C-G-G-G-(U-A-A)
    •      *3 amino acids, 4 total w stop codon
    •      *start is
  3. Typical protein
    contains 100-1000 amino acids
  4. Types of RNA
    • 1. rRNA
    • 2. mRNA
    • 3. tRNA
  5. rRNA
    • rRNA (ribosomal) - forms the large and small subunits of ribosomes 
    • Ribosome is the "workbench factory" for protein sythnesis
  6. mRNA
    • Messenger
    • the actual code
  7. tRNA
    • Transfer
    • brings amino acids to ribosomes (site of protein sythnesis)
  8. Main steps to protein sythnesis
    • 1. transcription
    • 2. translation
  9. FIND CARDS WITH
    • STEPS TO PROTEIN SYTHESIS
    •   TRANSCRIPTION AND TRANSLATION
    • POLYRIBOSOME
