Study Notes

Nucleus is the control center of the cell, responsible for all cellular activities.

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 stands for Deoxyribonucleic Acid.
DNA is the hereditary material that contains the complete set of instructions for developing a new cell or organism.

Heredity refers to the transmission of characteristics from parents to offspring.
Genetics is the science of heredity, studying the structure and behavior of genes.

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 (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 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.
