📖 1. Genetics

🔑 Key Concepts & Definitions

• DNA (Deoxyribonucleic Acid): Molecule containing genetic information in the nucleus of cells, structured as a double helix.
  Example: Human DNA carries instructions for building proteins.

• Gene: Segment of DNA that determines a specific hereditary trait, such as eye color.
  Example: The gene for blue eyes.

• Chromosome: Structure formed by condensed DNA, visible during cell division; humans have 23 pairs.
  Example: During mitosis, chromosomes are visible under a microscope.

• Heredity: Transmission of traits from parents to offspring through genes, involving alleles (different versions of a gene).
  Example: Passing on brown hair.

• Mutation: Change in the DNA sequence, which can introduce genetic diversity or cause genetic disorders.
  Example: A mutation leading to sickle cell anemia.

📝 Essential Points

• DNA Structure & Function: DNA's double helix structure allows it to store genetic information efficiently. Genes are specific sequences within DNA that code for proteins.

• Genetic Inheritance: Traits are inherited via alleles; dominant and recessive alleles influence trait expression. Offspring inherit one allele from each parent.
