AT CG 2 of 29 Proteins are _____ of _____ ____? polymers of amino acids 3 of 29 In humans there are how many different amino acids? 20 4 of 29 The specific order of amino acids determines what? the shape of the protein 5 of 29 The shape of the protein determines? its function 6 of 29 How does a cell read a DNA sequence? as triplets of bases 7 of 29 Each base triplet is called what? a codon 8 of 29 protein is needed for what three things? growth repair maintainence 9 of 29 It is also used to make what (2) hormones enzymes 10 of 29 PROTEINSYNTHESIS -------------------------- What is stage 1? transcription 11 of 29 Firstly, the base sequence of a _____ is _____? gene is copied 12 of 29 The DNA double strand will then ? split open 13 of 29 The bases will then? pair up 14 of 29 However what is different about the bases? the is no T 15 of 29 What is there instead? U (Uracil) 16 of 29 This pairs with? A 17 of 29 What is then made? a single strand 18 of 29 Of what? mRNA (messenger) 19 of 29 The mRNA will then pass out of ______ into the ______? out of nucleus into the cytoplasm 20 of 29 What is stage 2? translation 21 of 29 Here what will the mRNA attach to? a ribosome 22 of 29 Then _____ _____ will be brought to the ribosome on _______ molecules? Then amino acids will be brought to the ribosome on carrier molecules 23 of 29 These are called what? TRNA (transfer) 24 of 29 The ribosome will then read? the codon triplet of bases 25 of 29 And will assemble the amino acids? in the correct order 26 of 29 This creates a ________ chain? polypeptide 27 of 29 This chain is then ______ and _____ to make a ________? twisted and folded to make a protein 28 of 29 In a ______ shape which determines its _____? unique function 29 of 29
