Study Notes
Overview of Cell Structure
- Cells serve as the fundamental building blocks of all living organisms.
- Each cell functions independently and is responsible for various biological processes.
Nucleus
- Acts as the cell's control center, directing activities such as growth, metabolism, and reproduction.
- Contains genetic material that regulates cell function and heredity.
Chromosomes
- Thread-like structures located in the nucleus, composed of DNA and proteins.
- Carry hereditary information and are essential for cell division and genetic variation.
DNA
- Deoxyribonucleic acid is a double-helix molecule responsible for storing and transmitting genetic information.
- Serves as the template for the synthesis of proteins, influencing organism development and traits.
Genes
- Functional segments of DNA that specify instructions for producing proteins.
- Each gene affects particular traits and contributes to the overall genetic makeup of an individual.
Genetic Blueprint
- Cells contain thousands of chromosomes, with each chromosome housing hundreds to thousands of genes.
- The collective information within genes and DNA constitutes the blueprint for personality traits and health predispositions.
