Question 23 Correct Mark 1.00 out of 1.00 " Flag question A small section of Saccharomyces cerevisiae gene has the amino acid sequence valine, histidine, cysteine, and lysine. A mutation in the above section of the amino acid sequence resulted in the substitution of amino acid lysine with amino acid asparagine. The mutation in the antisense strand DNA of Saccharomyces cerevisiae gene described above involves a. the substitution of cytosine base from TTC v/ b. the substitution of guanine base from AAG c. the substitution of second thymine base from TTC d. the substitution of second adenine base from AAG Your answer is correct. DNA TTC mRNA AAG Amino Acid | Lysine A DNA sequence of TTC codes for the amino acid lysine. When the cytosine base from TTC is substituted to guanine, TTG, it would result in the amino acid asparagine. DNA TTG mRNA AAC Amino Acid | Asparagine The correct answer is: the substitution of cytosine base from TTC
