Study Notes
Cell Structure
- Nucleus is the control center of the cell, responsible for all cellular activities.
Chromosomes
- Chromosomes are found in the nucleus of the cell and consist of proteins and DNA.
- The number of chromosomes in the cells of a species remains the same, but is reduced to half in gametes (sperms or eggs) or spores.
DNA
- DNA stands for Deoxyribonucleic Acid.
- DNA is the hereditary material that contains the complete set of instructions for developing a new cell or organism.
Heredity and Genetics
- Heredity refers to the transmission of characteristics from parents to offspring.
- Genetics is the science of heredity, studying the structure and behavior of genes.
Cell Structure and Function
- The nucleus is the control center of the cell, responsible for governing all cellular activities.
- Chromosomes are found in the nucleus and consist of proteins and DNA.
DNA and Chromosomes
- DNA (Deoxyribonucleic Acid) is the hereditary material containing a complete set of instructions for developing a new cell or organism.
- Chromosomes contain genes, which act as instructions to make proteins.
- The number of chromosomes in cells of the same species remains constant.
- However, during gamete formation (sperm or egg cells in animals, spores in plants), the number of chromosomes is halved.
Heredity and Genetics
- Heredity refers to the transmission of characteristics from parents to offspring.
- Genetics is the science that studies heredity, focusing on the structure and behavior of genes.
- Genes are the basic physical and functional units of heredity, located on chromosomes.
