How does molecular genetics add to our understanding of genes is by simply </span>studying them. <span> Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. </span>This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. <span>And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.<span>

Para realizar la fotosíntesis las plantas necesitan varios elementos que se encuentran en el medio ambiente.
Energía luminosa: impacta sobre las hojas y es absorbida por el pigmento fotosensible de la planta, la clorofila.
Agua: La fotosíntesis requiere un suministro constante de agua. Ésta llega a las hojas a través de las raíces y tallos.
Clorofila: Pigmento de color verde contenido en el cloroplasto. Se encarga de la absorción de la luz, para llevar a cabo la fotosíntesis.
Dióxido de carbono: Es absorbido por unos minúsculos poros, llamados estomas, en la parte inferior de la hoja.
Oxígeno: subproducto de la fotosíntesis. Sale de las hojas hacia el exterior a través de lasestomas.
Helped to confirm that environmental changes cannot affect the characteristics of a species.
Optical telescope issues visible light emitted by a star to make it appear closer. Radio, Ultra Violet and infrared telescope issues the wavelength of light.
