Date Class Protein Synthesis Notes: Transcription and Translation Translation Name Review---DNA vs. RNA Steps of Protein Synthesis Step 1- Transcription Transcription is made from O Function: A single strand of Location: In the o Steps of Transcription 1. (an enzyme) attaches to DNA at a special sequence that serves as a "start signal". 2. The DNA strands are and one strand serves as a template. 3. The RNA bases attach to the complementary DNA template, and is made! 4. The RNA polymerase recognizes a 'stop' part on the DNA molecule and the new molecule. The mRNA leaves the and travels to the O Transcription Practice: Transcribe this strand of DNA into RNA (no T's in RNA!) DNA: A A T CTAGAT CATTA RNA: Step 2- Translation Function: Pieces of RNA make which then make O Location: In the O There are different types of RNA: 1. mRNA: messenger RNA ● (genetic code) from the nucleus to the 2. tRNA: transfer RNA Carries a ribosome (how to make proteins) amino acids to the ribosome
o Steps of Translation 1. 2. The ribosome looks for ● Codon: group of nucleotides on the messenger RNA that specifies one amino acid. 3. (transfer RNA) carries amino acids to the mRNA. 4. This tRNA has an • that matches the codon on the mRNA strand. group of 3 unpaired nucleotides on a tRNA strand. is dropped off and a chain forms. When the 5. Each chain is completed, it disconnects and makes a o Translation Practice: What amino acids do these codons stand for? 1. AUG- 2. GGA- 3. GAG- 4. CAA- 5. What amino acid does the anticodon CGU stand for? 6. Find the amino acid sequence for the following mRNA sequence (translation): AUGCGAC GAAUUUAA 7.
