Textbook Question
Chapter 14.1, Problem 3CC
DRAW IT The template strand of a gene contains the sequence 3’-TTCAGTCGT-5’. Suppose that the nontemplate sequence could be transcribed instead of the template sequence. Draw the nontemplate sequence in 3’ to 5’ order. Then draw the mRNA sequence and translate it using Figure 14.6Q. (Be sure to pay attention to the 5’ and 3’ ends, remembering that the mRNA is antiparallel to the DNA strand.) Predict how well the protein synthesized from the nontemplate strand would function, if at all
