  9. DNA Replication
    • The process in which DNA makes copied of itself.
    • This occurs in the nucleus of a cell.
  10. RNA stands for:
    Ribonucleic Acid
  11. 4 Types of Nitrogen Bases in RNA are:
    • Adenine

    • Guanine
    • Cytosine
  12. Three types of RNA are:
    • Messenger RNA (mRNA)
    • Transfer RNA (tRNA)
    • Ribosomal RNA (rRNA)
  13. mRNA is made in a process called _____.
    Transcription.
  14. Transcription occurs in the _____ of the cell.
    Nucleus.
  15. The strand of DNA being read during transcription is called the _____.
    Coding strand.
  16. Codon (define)
    • A group of 3 letters on an mRNA strand.
    • Each codon represents an amino acid.
  17. Translation takes place in the _____ of the cell.
    Ribosomes.
  18. tRNA drops _____ onto the mRNA.
    Anti-codons.
  19. When tRNA deposits anti-codons, this makes _____.
    Amino acids.
  20. The chemical formula for a phosphate group is:
    PO4
  21. The 2 functions of DNA are:
    • Instructions for the synthesis of all proteins.
    • Copies itself to be passed on to offspring.
  22. Function of RNA is:
    To assist in protein synthesis.
  23. Translation (define)
    A strand of RNA is read one codon at a time and amino acids are deposited to make proteins.
  24. Stop Codon is:
    UAG
  25. Start Codon is:
    AUG
