Presentation Transcript

  1. RNA Translation and Transcription

  2. DNA replication starts with an enzyme called Helicase, The Helicase separates the Hydrogen bonds that are in between the two complementary bases. This acts like a zipper DNA REPLICATION

  3. The DNA polymerase binds to a single strain of the old (parent) DNA, and uses it as a template to makes a new chain. • The result is a new strain that is half old half new.

  4. Replication means exact copies of DNACopies are used for new cells for growth and repairThe sugar in DNA is deoxyribose.

  5. Ribonucleic acid - Stores and transfers genetic information essential for making proteins. • Sugar phosphate backbone (sugar = ribose) • One stranded • Four bases • Adenine, Guanine, Uracil, Cytosine RNA

  6. Transcription is the writing a message to send out of the nucleus

  7. This is the process that RNA copies the genetic information from DNA and transfers it to the cytoplasm where it can be used to produce proteins. Transcription

  8. Once RNA is out of the nucleus, it can be read in segments of three bases at a time. It will then code for an amino acid, which will combine to make a protein Translation

  9. Change in DNA bases • Can be random or caused by the environment (ex: radiation) • Can make a significant change or very little change to organism • Sometimes is bad, sometimes can be good Mutations

  10. Front and Front Gators

  11. Two faced kitten

  12. Lots of Frog Legs

  13. A helpful mutations allowed this dog to save the children of Nome Alaska

  14. REMEMBER

  15. Practice
