8 The sequence оf bаses in DNA determines the sequence оf аminо аcids in a polypeptide. The table shows four amino acids and their genetic codes. Amino Acid Genetic Code alanine (Ala) GCT or GCC or GCA or GCG lysine (Lys) AAA or AAG serine (Ser) AGT or AGC or TCT or TCC or TCA or TCG tryptophan (Trp) TGG 8 Diagram 8.1 (see addendum Question 8) shows a DNA base sequence. 8.1.1 Complete the diagram to show the sequence of amino acids coded by this DNA base sequence. Write down the order of the amino acids on your answer sheet. (1) 8.1.2 Explain why only five amino acids are coded by this sequence of bases. (2) 8.2 Explain why some amino acids, such as alanine, have more than one genetic code. (3) 8.3 Of the 64 possible genetic codes, 61 code for amino acids. 8.3.1 Calculate the percentage of genetic codes that code for amino acids. Give your answer to four significant figures. (1) 8.3.2 Explain the role of the other three genetic codes. (2) 8.4 Messenger RNA (mRNA) and transfer RNA (tRNA) are involved in the synthesis of a polypeptide chain from DNA. Which row of the table shows the codon on mRNA and the anticodon on tRNA that correspond to tryptophan? Choose the correct option between A, B, C and D. (1) Codon on mRNA Anticodon on tRNA A ACC TGG B ACC UGG C UCC AGG D UCC TGG
