Why do you think the terms "on" and "off" are written under genes ?
Genes are DNA segments that are present on chromosomes and regulate to produce different proteins, so "on" and "off" are written to make the gene ready and not to produce protein.
What is the regulation of genes?Genes produce proteins, this protein has various functions in the cell at a specific time duration in the organism's life, so this process is regulated at several stages so every protein is made in the perfect amount and at the exact time.
The regulatory proteins are responsible for these processes to make genes turn on and off conditions which produce appropriate protein at times when it is needed this decides the cell's condition at various stages.
Therefore, the terms "on" and "off" are written under genes for gene regulation in the cell.

Cuáles son los beneficios y daños que producen las siguientes sustancias. Dióxido de carbono Monóxido de carbono Óxido nítrico Dióxido de azufre Monóxido de hierro
Answer and Explanation:
Dióxido de carbono:
- Beneficio: Gas que se encuentra en la naturaleza y que resulta indispensable para las plantas para llevar a cabo la fotosíntesis. No nocivo en concentraciones entre 300 ppm a 550 ppm.
- Daño: A elevada concentración, cercanas a 30.000 ppm, es considerado contaminante y provoca alteraciones como mareos, dolor de cabeza, somnolencia, problemas para respirar. A concentraciones superiores puede causar asfixia.
Monóxido de Carbono:
- Beneficio: En muy bajas concentraciones puede ser beneficioso para tratar algunas enfermedades vasculares. También puede ser utilizado como marcador o indicador de salud al medir el monóxido de carbono exhalado.
- Daño: Produce intoxicación y causa dolor de cabeza, mareos, debilidad confusión, entre otros. En alta concentración, y sin ser advertido, puede incluso llevar a la muerte. Es un gas altamente inflamable por lo que a parte de las afecciones a la salud por inhalación, también puede provocar explosiones.
Óxido nítrico:
- Beneficios: Posibilita una mayor recepción de nutrientes y oxigeno en músculos, favoreciendo la vasodilatación y la irrigación sanguínea. Regula la presión arterial.
- Daño: En exceso, en una persona que no lo necesite, puede causar daños en los riñones e hígado y puede alterar el pH interno.
Dióxido de Azufre:
- Beneficios: En baja concentración, puede actuar como conservante impidiendo la aparición de bacterias, lo que puede resultar de utilidad en algunos alimentos.
- Daño: En estado gaseoso involucrado en el cambio climático y en la lluvia ácida. Provoca irritación de ojos, irritación de vías respiratorias y de membrana mucosa, y piel. También puede provocar dolores de cabeza, nauseas, y otros malestares. A través de las vías respiratorias, pasa al sistema circulatorio.
Monóxido de hierro:
- Beneficios: Muy utilizado en la industria. Es utilizado en cosmética y como pigmento para distintas utilidades. El oxido de hierro colabora en la limpieza de contaminación ambiental por los gases producidos por vehículos y fábricas.
- Daños: La inhalación crónica de monóxido de hierro puede resultar en siderosis, y puede resultar en cáncer pulmonar.
