Study Notes

Human Genetics Quiz

DNA Function (Question 1): DNA controls the timing, quantity, and structure of protein production. DNA does not control the quality of protein production.

Genetics Study (Question 2)

Genetics Definition: The study of heredity, encompassing the functions of proteins, single genes, specific DNA sequences, and the overall function of heredity. The study of how genes work is included.

Genetic Conditions (Question 3)

Genetic Variant Pairing: Sickle Cell Anemia is paired with Cystic Fibrosis, not Down's Syndrome.

Single Gene Conditions (Question 4)

Single Gene Change Pairing: Achondroplasia is paired with Down's Syndrome

Clinical Implications of Human Genetics in Dentistry (Question 5)

False Pairing: The FALSE pairing is Ethnic impact is NOT a clinical implication of human genetics in dentistry. Social, future prevention and legal/ethical impacts ARE considered.

Tooth Conditions Not Influenced by Human Genetics (Question 6)

Not Genetically Influenced: Enamel demineralization is NOT a genetically influenced tooth condition.

Mendel's Principles of Inheritance (Question 7)

False Statement: Phenotypes are NOT distinct; they are a combination/expression of traits. Alleles have alternate forms and segregate specifically.
