In the absence of substance M, a hypothetical LM operon is turned off. If substance M is abundant, it can bind to the repressor,
Andrei [34K]

Answer:Inducible;inducer

Explanation:

Induction is the phenomenon of increased synthesis of protein or and enzyme in response to certain signal. Such enzymes are called inducible and the signals are called inducer. Induction is turning ''on''the switch of a gene.

When M is present in the medium, M binds the repressor protein. The repressor-M complex is inactive which does not bind to the operator region of LM. Now RNAP can transcribe the structural genes of LM.

M switches the gene ''on''. Hence M is an inducer of LM. LM is an inducible operon

¿Cómo explicaría Lamarck el origen y la expansión de estas bacterias resistentes? ¿Cómo explicaría
Anuta_ua [19.1K]

La teoría de la evolución de Lamarck se basa en la capacidad de los organismos para cambiar físicamente debido a las adaptaciones en su entorno para garantizar su supervivencia. Esto es evidente en la propagación de los determinantes de resistencia a los antibióticos entre las bacterias. La capacidad de las bacterias para desarrollar nuevos mecanismos de resistencia para sobrevivir a los antibióticos radica en su capacidad para adquirir genes que los ayuden a este respecto a través de la transferencia horizontal de genes y la adquisición de plásmidos. Mecanismos como bombas de eflujo y plásmidos les ayudan a sobrevivir en medio de antibióticos. Transmiten estos materiales genéticos a sus descendientes, lo que garantiza que continúen sobreviviendo y no se extingan a pesar de la presencia de antibióticos.

El dawrnismo claramente reclama la selección natural. Por lo tanto, si un organismo no evoluciona o adquiere características especiales para ayudarlo a adaptarse, competir y sobrevivir en su entorno, se extingue. Solo aquellos que adquieren estas habilidades sobreviven y se reproducen en el medio ambiente.
