In DNA, the strand defined as the coding strand is the one with the same
sequence as the mRNA that is eventually derived from that segment of DNA. The
sequence shown in the BRCA2 sequence file is that of the coding strand (by
convention). Also by convention, that sequence is represented in the 5' to 3'
direction. The nucleotide provided as a starting point should thus serve to orient
your sequence from top to bottom.

Congratulations, you have properly constructed the DNA sequence of this portion of the BRCA2 gene. Now build the mRNA that would be transcribed from the template strand of the DNA. Start by placing the top ribonucleotide and work your way down.
Great! You have properly constructed the mRNA sequence for this portion of the BRCA2 gene and have successfully completed this portion of the exercise. Click continue to proceed.

Objective
Build DNA and RNA strands based on the BRCA2 coding sequence, and understand important structural features of DNA and RNA polynucleotides.
Reward
Collect the DNA/RNA Structure token and unlock the DNA Polymerase simulation marker.
Congratulations, you have successfully completed the activity! Your score shows you have a solid understanding of DNA and RNA structure. Click the button below to collect the DNA/RNA Structure token and unlock the marker for the DNA Polymerase simulation.
Congratulations, you have successfully completed the activity! However, your score indicates your knowledge of DNA and RNA structure has some uncertainty. Try the exercise again to collect the DNA/RNA Structure token and unlock the marker for the DNA Polymerase simulation.
Congratulations, you have successfully completed the activity! However, your score indicates your knowledge of DNA and RNA structure is not adequate. Consider reviewing your text, and then try the exercise again to collect the DNA/RNA Structure token and unlock the marker for the DNA Polymerase simulation.
