On the DNA EVIDENCE SHEET (page 27), you will see the gene involved in the origin of melanism in some rock pocket mouse populations, melanocortin receptor 1, or
MC1R for short. The complete gene is 954bp in length. Scientists have collected this data from a population of primarily dark-colored mice living in an area of
basalt in Arizona called the Pinacate lava flow, as well as from a nearby light-colored population and some other areas.
Summarize what you just read.

DNA is double-stranded and consists of a “sense strand” and an “antisense strand.” The sense strand (top row below) is what you see on the data sheet, but
you transcribe mRNA from the antisense strand. Take the first 20 triplets (groups of 3) and add them to the DNA boxes (top row below), crossing them off as you go to avoid
errors. Do this for both the light mouse. Write done, when this is complete.
