Look at the diagram above and notice that the allele for the brown or tan is far away from the centromere and thus the crossover will more than likely INCLUDE the color allele (black line).

This is figure 15.12 of your text. This was a genetic map made from recombinant frequencies or percentages. Notice the the Aristae Gene has a 0 on this gene map of a single chromosome of the drosophila. This gene is the closest to the Centromere. The Body Gene is 48.4 distance away from the Aristae Gene and thus would have a much higher chance of recombinants. The other genes are even farther away and almost certainly are always included in a cross over event and are always moving to another chromosome. We would say these genes are unlinked even being on the same chromosome. |

The code will go in order but it will have many UTR’s (Untranslated REgions) that are not part of the code and these are INTRONS!!!!
After you have highlighted all of the EXONS Physically cut away all of the INTRON in between the start and stop codon and retape (splice) the RNA back together so that there is a continuous code of EXONS from start to stop. At this point you are acting as snRNA (snurps) in a splicesome!
Your pre-mRNA IS NOW a mRNA and can leave the nucleus to begin Translation.
9. Roll up your DNA and completed mRNA and place on top of your packet with group names and return this back to the lab area you picked up your work today.

*Remember to include start and stop codons, any additional UTR’s that are necessary, other additional items that you may have to add. Color code your DNA strand and your completed mRNA molecule.
For instance the Exons on both molecules should be highlighted with the same color. Please take a picture of:
A) DNA molecules (both strands)
B) pre-RNA strand
C) completed mRNA molecule
