The cell theory states that absolutely all living beings are composed of cells, for which all cells must contain the necessary structures to metabolize (nourish) and self-perpetuate (reproduce) as the cell nucleus, where the DNA is store.
Cell theory focused the efforts of biology on the cell as the minimal structure to sustain life.
- The vital functions of organisms take place within cells through biochemical processes, and are controlled by substances secreted by cells.
- Cells have diverse structures and delimited sectors that allow them to fulfill vital functions in the entire organism: birth, nutrition, metabolism, reproduction, growth, death.
- These processes also depend on important cellular structures, such as the cell nucleus, where the DNA of the entire species is contained.
Therefore, we can conclude that the cell theory allowed us to understand the dynamics and processes of the cell.

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.
<h3>What are homeotic genes?</h3>
- Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
- These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
- Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
- Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
- The loss of function of any of the gene changes the body pattern and affects the development.
