Question
il r nuclebtide sequence is given without given the orientation, the default is that the 3' end is written on the left hand side. a. True False Part IV Questions 37 and 40 refer to the statement below: Drawn below is part of a wild-type gene. The DNA sequence shown encodes the last part of a protein that is 380 amino acids long. The underlined codon (the first three letters shown) indicates the correct reading frame of this gene. The lower strand of the gene is used as the template during the transcription of this gene. There are five highlighted base pairs referred to as A, B, C, D and E, respectively, as marked below the sequence. (Hint stop codons are TAA, TAG and TGA) GCTAAGTATTGCTCEAGATTAGCATGATAATAACTGG-3 38. Indicate one base pair that you could change to make a mutant form of the gene that encodes a protein of 381 amino acids. 39. Can you use G to substitute the base in the sense strand you would change in the question immediately before this? Bubble in A if G can be used, or bubble in B if G cannot be used. 40. Indicate the base pair where you could add one extra base pair to its left in order to make a mutant form of the gene that produces a protein of 373 amino acids. 41. Refer to the question immediately before this, which of the following base you could add to the DNA sequence: A. Guanine B. Adenine C. Thymine D. Cytosine Bonus questions 1. Write a python script that asks the user to input aExplanation / Answer
1) look at A nucleotide in TGA codon highlighted as D substitute this A with G in the sense strand so that it can code for an amino acid and total length of protein becomes 381 aa
2) see answer number 1
3) add an extra nucleotide thymine left to adenine highlighted as A in the sense strand, now the frame will shift and the codon next to GCT will be TAA which is stop codon.
4) thymine
