Your high school crush is working with a breed of guinea pig in which the side on which the hair parts down the back is inherited, and it can either be on the left or the right. Left-parting appears to be dominant in this system. S/he/they crosses true-breeding parents that are phenotypically left-parters and gets a generation of right-parters. Inbreeding the F1 produces a generation that consists entirely of left-parters.
f. How is this trait transmitted?
g. What are the genotypes of the parents and the genotypic ratios of the F1 and the F2?
h. What was the genotype of the mother of the original female parent?

Regarding the growth and development of the face and occlusion from infancy to adolescence answer the following questions:
A) Describe the features of the pre-dental period and the various developmental abnormalities that may be seen in this period.
B) Describe the transition from the mixed dentition to the permanent dentition phase and the variations that may occur.
C) Using five examples of self-correcting malocclusions present during the development of the occlusion, describe the mechanisms of how each of these takes place.
D) Explain how the sequence of eruption of the permanent dentition plays a role in the establishment of a normal occlusion.

Transcription: From DNA to RNA
1. Define a gene.
2. How does RNA differ from DNA?
3. Briefly describe the process of transcription.
4. Describe the process of transcription as it occurs in prokaryotes.
5. What is the role of the promoter?
6. Describe the process of transcription as it occurs in eukaryotes.
7. What is the role of the transcription factors? A mutation exists in transcription factors that causes them to bind slightly downstream of the TATA box, causing them to cover the first 3 nucleotides of a gene. RNA polymerase can still transcribe the gene to mRNA, but it misses the first 3 nucleotides. How would this impact translation?
8. What is the role of kinase and phosphatase in eukaryotic transcription?
9. How does RNA polymerase know which strand of the DNA to transcribe? What would happen if it chose the wrong strand?
10. Why does translation in prokaryotes begin before transcription is complete?
11. What must occur in eukaryotes before translation can begin?
12. How are the ends of the mRNA modified in eukaryotes?
13. What are introns and exons?
14. Describe the process of RNA splicing.
15. What is the role of alternative splicing in evolution?
16. Compare and contrast transcription in prokaryotes and eukaryotes.
