Question
These question were on my Genetics Exam. I want to know what the correct answer so I can use it to study for my finals coming up.
11. (5 points0 Below is a sequence of double-stranded DNA from a bacterial gene. +1 of the transcribed sequence is indicated and highlighted in bold type. Give the first ten bases of the RNA that would boe produced by transcription. +1 5-GCGCAAGCTTATCCTGCTGTACCAGAcCCTTGGCACCATTATACAGACCTGTACACTTGTCAAATTA-3 3"-CGCGTTCGAATAGGACGACATGGTCTGGGAACcGTGGTAATATGTCTGGACATGTCAACAGTTTAAT-5 16. (8 points) The following is part of the sequence of the reading frame of a gene. The codons are separated by slashes. 5'-GGA/ATC/CGA/AAA-3 The following is a mutant version of the above sequence 5'-GGA/ATC/GGA/AAA-3 A. What is the term for how this mutation changes the polypeptide encoded by this open reading frame? B. Is this mutation a transition or a transversion? (cirele one) 17.

GGA/A TC/TGA/AAA-3 , A. What is the term for how this mutation changes the polypeptide encoded by this open reading frame? B. Is this mutation a transition or a transversion? (circle one)Explanation / Answer
11- RNA sequence: 3'AACCGUGGUAAUAU5'
16. cga TO gga WILL CHANGE FROM arg TO val in the polypeptide chain. hence this is a sence point mutation which can change the protein structure.
C to G is a transversion mutation because transition is exchange between 2 rings or purine or one ring of pyrimidine. transversiond involve exchange between purine for pyrimidine.
17. CGA to TGA changes Arg to Trp. it is also a sense mutation
C to A is also a transversion mutation
