    DNA and RNA ClareBear.

    Does anyone have a summary of Translation and Transcription? I am really confused of how to answer the exam questions.

      Transcription- code on DNA copied onto mRNA

      Translation- code on mRNA is converted into a chain of amino acids

      protein synthesis:

      1) DNA strands unwind and separate

      2) the code in one DNA strand Is copied onto the base sequence in mRNA this is called transcription

      3) mRNA moves into the cytoplasm and goes to a ribosome

      4) ribosomes are made mainly of ribosomal RNA

      5) the mRNA strand moves into a ribosome

      6) there are a large number of transfer RNA molecules in the cytoplasm reach tRNA carried a specific amino acid

      7) triplets or codons on the mRNA strand attract complementary triplets on tRNA molecules

      8)each tRNA carries its own amino acid

      9) the amino acids are detached from their tRNA molecules and bonded together to form the new protein

      10) the protein then folds into the correct 3D shape to allow it to function properly
