Presentation Transcript


  1. RNA

  2. Ribonucleic Acid • Single nucleotide strand • Sugar: Ribose • 4 Bases: • A: Adenine • G: Guanine • C: Cytosine • U: Uracil • U replaces T • Three Types of RNA

  3. Messenger RNA • mRNA • Function: Reads the DNA (ATCG) and carries its message to a ribosome • Location: Starts in nucleus… moves to ribosome U A C C A U G G U A

  4. Transfer RNA • tRNA • Function: Transfer amino acids found in the cytoplasm to the ribosome • ATP needed • Amino acids will be used to make a protein • Location: Cytoplasm

  5. Ribosomal RNA • rRNA • Function: Used to build ribosomes • Location: Cytoplasm • Ribosome: Makes proteins

  6. Defined: Process of making mRNA from DNA Step 1: RNA Polymerase separates the DNA nucleotides Step 2: Free floating RNA nucleotides match with the DNA Reminder: U replaces T Step 3: mRNA breaks free in separate pieces Step 4: mRNA processing takes place Unused portions (introns) are removed and the used portions (exons) bond together Step 5: Final mRNA strand travels to ribosome Step 6: DNA recombines to be used again U Transcription G G C A A G U C A U U C

  7. Transcription Animation

  8. Step 2: Free floating mRNA nucleotides match up Step 1: RNA polymerase splits the DNA Step 5: mRNA travels to ribosome and DNA reconnects Step 3: mRNA breaks free Step 4: Remaining exons bond together RNA polymerase The End! You have no idea how long that took to create!

  9. Double Stranded Sugar: Deoxyribose Bases: A T C G Location: Nucleus DNA vs. RNA • Single strand • Sugar: Ribose • Bases: A U C G • Location: Nucleus & Cytoplasm
