  1. How are DNA and mRNA alike?
    They are both made of nucleic acid
  2. How are DNA and mRNA different? (How many strands, Nitrogen Bases, Location)
    DNA: 2 Strands, ATGC, Nucleus

    mRNA: 1 Strand, AUGC, Ribosome+Nucleus (It moves around, while DNA can't)
  3. How many strand of mRNA are transcribed from the two "unzipped" strands of DNA?
    1
  4. If the following were part of a DNA chain, what mRNA bases would pair with it to transcribe it?

    A-T-G  G-C-A  T-A-C
    U-A-C  C-G-U  A-U-G
  5. If DNA is described as a double helix, how should mRNA be described?
    Uni-Helix/ Single- Helix
  6. Which nitrogen base replaces Thymine in tRNA?
    Uracil
  7. Name and describe the two types of RNA involved in protein synthesis?
    • mRNA: Messenger
    • tRNA: Transferer
  8. What is located at each end of tRNA molecule?
    Amino-Acid and Anti-Codon
  9. Where must an mRNA attach before protein production can begin?
    Ribosome
  10. How many nitrogen bases are needed to specify and mRNA codon?
    3
  11. What is the relationship between amino acids and proteins?
    The amino acids create the proteins
  12. What is the protein synthesis flow chart?\
    In order?
    • 1. (First Part)Transcription
    • 2. (Take place in the) Nucleus 
    • 3. (Where DNA is decoded into)mRNA 
    • 4. (Leaves through the) Nuclear Pore
    • 5. (Goes to a) Ribosome
    • 6. (The 2nd part of Protein Synthesis) Translation
    • 7. (Where) tRNA anticodons bond with...
    • 8. mRNA codon
    • 9. (Then) Ribosome
    • 10. (Create) Peptide bonds
    • 11. (Between) Amino Acids
    • 12. (Creating a) Protein!!
