Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Genetic Inheritance
Genetic inheritance refers to the process by which traits and characteristics are passed from parents to offspring through genes. This fundamental concept underpins much of genetics, explaining how variations arise and are maintained in populations. Understanding inheritance patterns, such as Mendelian inheritance, is crucial for grasping the significance of genetic discoveries.

Molecular Genetics
Molecular genetics focuses on the structure and function of genes at a molecular level. It encompasses the study of DNA, RNA, and protein synthesis, revealing how genetic information is encoded, replicated, and expressed. Breakthroughs in this field, such as the discovery of the double helix structure of DNA, have had profound implications for biology and medicine, often leading to Nobel recognition.
