Genes are the basic unit of heredity that are passed down from parents to offspring. They are made up of DNA and contain the instructions for building and maintaining an organism. Genes determine various traits such as eye color, hair color, and susceptibility to certain diseases.
Key Concepts
What are Genes?: Genes are segments of DNA that contain the instructions for building and maintaining an organism.
Functions of Genes: Genes determine various traits and characteristics of an organism, including physical features and susceptibility to certain diseases.
Gene Expression: The process by which the information in a gene is used to direct the construction of a protein, which then carries out a specific function in the body.
Genetic Variation: The diversity of different genes in a population, which contributes to the uniqueness of individuals.
Genetic Disorders: Abnormalities or mutations in genes that can lead to inherited diseases or conditions.
Study Guide
Here are some key points to focus on when studying genes:
Understand the structure of DNA and how genes are composed of DNA.
Learn about the process of gene expression and how genes direct the synthesis of proteins.
Explore genetic variation and how it contributes to differences among individuals.
Examine examples of genetic disorders and their impact on individuals and families.
Consider the ethical implications of geneticresearch and technologies.
Remember to review and understand the role of genes in inheritance and how they contribute to the traits and characteristics of living organisms.
