Write out the complementary strand of DNA below the strand shown and be sure to label the 5’ and 3’ ends of the complementary strand.

There are six possible reading frames in double-stranded DNA. Using the genetic code, translate all possible reading frames of this DNA sequence.

+1 R-M-L-I-P-C-S-A-Y-N-P-A-A-S-S-A-G-G-I-L
+2 V-C-STOP-Y-H-V-P-R-I-T-Q-P-P-V-P-L-A-A-F
+3 Y-A-N-T-M-F-R-V-STOP-P-S-R-Q-F-R-W-R-H-F

-1 STOP-N-A-A-S-G-T-G-G-W-V-I-R-G-T-W-Y-STOP-H-T
-2 K-M-P-P-A-E-L-A-A-G-L-Y-A-E-H-G-I-S-I
-3 K-C-R-Q-R-N-W-R-L-G-Y-T-R-N-M-V-L-A-Y

Which of the reading frames (if any) of the reading frames you translated is an open reading frame, i.e., does not contain a stop codon?

Frames +1, -2, and -3
