Study Notes
Somatic Cells Overview
- Somatic cells are non-reproductive cells found throughout the body, excluding gametes.
- They are diploid, possessing two of each chromosome type, totaling 46 chromosomes (23 homologous pairs).
- Somatic cells are located in various tissues and organs, playing essential roles in bodily functions.
Division and Differentiation
- Somatic cells divide through mitosis, a process that allows for growth and tissue repair.
- During mitosis, DNA replicates, increasing the quantity of genetic material before nuclear division occurs.
- This ensures that each daughter cell receives an identical set of 46 chromosomes, maintaining the diploid chromosome number.
Chromosome Structure
- Each pair of chromosomes contains the same genes in the same positions but may differ in alleles, contributing to genetic diversity.
- Somatic cells, except for reproductive cells, are derived from stem cells.
Growth and Repair
- Somatic cells actively divide during periods of growth and repair, adapting to the body's needs.
- They differentiate to form various types of body tissue, each performing specific functions necessary for overall health.
