Genetic Inheritance (LC 2027) (Leaving Cert Biology): Flashcards

Structures in the nucleus storing genetic information

Thread-like form of chromosomes when cells aren't dividing

DNA molecule wrapped around histone proteins

Double helix

46 per cell (23 in sex cells)

Section of DNA coding for a specific protein

Basic units of inheritance

Complete set of all genetic material in an organism

Scientific study of the entire genome

Passing of nuclear DNA from parents to offspring through gametes

Specialised cells for reproduction (sperm, egg, pollen, ovules)

Study of how genes and traits pass down generations

Study of trait inheritance without changing DNA sequence

Chemical groups attach to DNA, turning genes off
