Unformatted text preview: amino acid. A2) a) This deletion does not produce a frameshift because even though the nucleotides deleted is still not divisible by three, the start codon appears after the deletion so the reading frame would not be thrown off. b) It expresses no functional alpha subunit because the proper amino acid sequence was changed after the deletion of the +22 and +23 nucleotides. A3) A to C : no effect because of its location in the promoter T to C: no effect because introns are excised out during transcription GCC to GCT : no effect because GCT would still translate as GCU which codes for the same amino acid AGG to CGG: no effect because they both code for Arg GCU to GGU: no effect because position 306 is not a conserved sequence...
