Presentation Transcript

  1. RNA and Transcription

  2. RNA V.S. DNA • Different sugar • RNA has Ribose instead of deoxyribose. • Different base pair • RNA has Uracil instead of thymine. • Different structure • RNA has a Single helix instead of double.

  3. Three types of RNA • mRNA (messenger) • “transcribes” DNA in the nucleus and brings code to the ribosome • tRNA (transfer) • Brings amino acids to the ribosome to make protein • rRNA (ribosomal) • Part of the ribosome structure

  4. transcription When mRNA copies the “code” for a gene from the DNA in the nucleus. To bring the information to the ribosome to make protein. Making mRNA

  5. Steps of transcription DNA has “promoters” sites where RNA polymerase bind to DNA. DNA untwists and unzips in area of molecule where the code for a certain protein is held. RNA polymerase adds complementary base pairs Stops when reaches “termination signal” RNA is released from DNA and leaves the nucleus Making mRNA

  6. Summarize what you have learned How is RNA different than DNA? What is Transcription? What are the steps of transcription? Write a paragraph and use a diagram in your explanation
