DNA's role in protein production?

DNA ensures the accurate creation of proteins, but it does not inherently control the quality.

What is genetics?

Genetics studies genes, heredity, and variation in organisms. The function of proteins falls under biochemistry or molecular biology.

Genetic conditions pairing

Down's Syndrome results from an extra copy of chromosome 21 (trisomy 21) and Sickle Cell Anaemia is caused by a mutation in the beta-globin gene.

Single-gene genetic conditions

Both Cystic Fibrosis and Achondroplasia are caused by mutations in a single gene.

Tooth conditions NOT influenced by genetics?

Enamel demineralization is primarily influenced by environmental factors (diet, oral hygiene) rather than genetics.

Mendel’s Principle of Inheritance

Mendel's Principle of Segregation states that allele pairs separate during gamete formation, ensuring each gamete receives only one allele per gene. Alleles segregate randomly.
