1. Fill in the blanks in the table below regarding the similarities and differences between DNA replication and transcription. (10 marks) DNA replication Transeription Polymerase moves along DNA template from 5 to 3' or 3 to 5"? What is the molecule synthesized? Is primase required? (Yes/No) Polymerase has 3 to 5' exonuclease activity? (Yes/No) Is the molecule synthesized complementary to the template? (Yes/No) 2. a. Below is a portion of a bacterial chromosome that contains a gene. The promoter region and the +1 base pair are indicated, as well as the direction (5' and 3') of the two DNA strands. (12 marks) +1 -10 -35 .3"TTGCATCCGAAACGTACGATCGATESGCCGACITATTACCATCGGACTACTGCGTCGTAGC5'.. S'AACGTAGGCTTTGCATGCTAGCTALLOGGCTGHATAATSCTAGCCTGATCACGCAGOTCG3". () Write the first 12 nucleotides of the RNA molecule transcribed from this gene. Be sure to indicate the 5' and 3' ends from left to right of the RNA strand. (2 marks) (ii) Explain why the Start codon does not appear in the first three nucleotides of the sequence transcribed in (1). (1 mark) b. Below is the sequence of DNA template of a gene. 5' ATGTACAAGGTCGGATGA 3' (6) Write the sequence of RNA transcribed from this template. Indicate the 5' and 3' ends from left to right of the RNA sequence. (2 marks) (ii) Under the RNA sequence in (i), write the corresponding anticodon sequence. Be sure to indicate the 5' and 3' at the two far ends of the anticodon sequence. (2 marks) (iii) Under the anticodon sequence in (ii), write the corresponding amino acids coded. Use 1-letter abbreviation to represent the amino acids. Also indicate the N-terminus and C-terminus in this peptide (5 marks)
