Transcript of "Dna to rna to amino acids"

  1. 1. DNA to RNA to Amino Acids Creating the components of life
  2. 2. What is an Amino Acid? 1. Proteins are made of amino acids. 2. DNA is a prisoner of the nucleus 3. For genetic information to leave the cell it must be copied into RNA An amino acid is the building block for a protein
  3. 3. RNA 4. RNA is also made of nucleotides. Each nucleotide is made of: a) Ribose sugar b) Phosphate Group c) One of four nitrogen bases: Adenine, Cytosine, Guanine, or URACIL 5. RNA is a single strand of nucleotides (DNA is a double strand)
  4. 4. Types of RNA 6. Three types of RNA: a) Messenger RNA (mRNA); shape: linear a) Carries code for protein synthesis into cytoplasm b) Ribosome RNA (rRNA); shape: a) Combines with protein to form a ribosome (where protein is made) c) Transfer RNA (tRNA); shape: cloverleaf a) Carries amino acid to ribosome
  5. 5. Proteins 7. RNA turns genetic information stored in DNA into proteins What do proteins do? Proteins help with metabolism, cell shape, signaling, responses, cell cycle, and form the basic building blocks of life Protein triose phosphate
  6. 6. Think-Pair-Share • From what we’ve discussed so far what is one thing you… ▫ Wonder ▫ Don’t understand ▫ Find interesting ▫ Would like to know more about Write your thoughts in the box provided
  7. 7. 8. Steps to Protein Synthesis A. Transcription: A. mRNA is copied from DNA. B. Ribbon of mRNA slips out of nucleus and attaches to a ribosome. C. Each set of three nucleotides of mRNA are called codons and code for a specific amino acid
  8. 8. B. Translation: A. tRNA has a sequence of three bases that are complimentary (match) to the mRNA’s codon. B. tRNA brings amino acid from the cytoplams by matching its anticodon to the mRNA C. Ribosomes provide a site for protein synthesis to occur D. The chain of amino acids created by transcritpion and translation is called a protein.
