Question

(1) Below is a segment of the coding sequence for a gene. The promoter is shown at the left indicating the direction of transcription. Assume that the correct reading frame starts with the first 3 nucleotides. Fill in the mRNA sequence, the amino acid sequence, and the sequence of the anticodons corresponding to each codon. Clicker questions will ask for this info based on the AA number indicated. TTCTCCGTATTGATCG TG mRNA sequence: Amino Acid sequence: tRNA anticodon: 4 (2) Below is a segment of the same coding sequence as in 1, but there has been a single nucleotide mutation at the position in bold. Fill in the mRNA sequence, the amino acid sequence, and the sequence of the anticodons corresponding to each codon. Clicker questions will ask for this info based on the AA number indicated. 3' 5TT CT CCG TATTGCT CGTG mRNA sequence: Amino Acid sequence: tRNA anticodon: 4 6
