RNA

RNA. Ribonucleic Acid Single-stranded Contains uracil instead of thymine. RNA. RNA like DNA is composed of nucleotides - 5 carbon sugar (ribose) phosphate group nitrogenous bases ( adenine, uracil, guanine, and cytosine). Give the complementary strand of RNA.

Presentation Transcript

  1. RNA • Ribonucleic Acid • Single-stranded • Contains uracil instead of thymine

  2. RNA • RNA like DNA is composed of nucleotides- • 5 carbon sugar (ribose) • phosphate group • nitrogenous bases ( adenine, uracil, guanine, and cytosine)

  3. Give the complementary strand of RNA. • DNA-ATGCATTACGAAGCTT • RNA-____________________

  4. What are 3 major differences that make RNA different from DNA? • Sugar-Ribose (RNA) • Nitrogenous Base- Uracil (RNA) • Single-Stranded (RNA)

  5. There are 3 main types of RNA: A. Ribosomal RNA (rRNA) – combines with proteins to make ribosomes B. Transfer RNA(tRNA) – during translation, it transfers each amino acid to the ribosome to make proteins C. Messenger RNA(mRNA) – carries copies of instructions to make new DNA

  6. Similarities and differences between RNA and DNA

  7. Similarities and differences between RNA and DNA

  8. Transcription • During transcription, RNA polymerase binds to DNA and separates the DNA strands. RNA polymerase then uses one strand of DNA as a template from which nucleotides are assembled into a strand of RNA. • So, RNA is making a single-stranded copy from DNA that takes information out of the nucleus.

  9. Transcription: RNA molecules are produced by copying part of the nucleotide sequence of DNA into a complementary sequence in RNA. • Instead of DNA polymerase that is used in replication, RNA polymerase is used to begin the transcription process.

  10. WHAT IS THE RELATIONSHIP BETWEEN RNA and DNA? • RNA can’t be copied without DNA. • DNA can’t send it’s information through the cell without RNA.

  11. Where does replication take place? • Nucleus • Where does transcription take place? • Nucleus • Where does translation take place? • Ribosome
