Abstract
La meiosis es un proceso de división celular especializado que implica una replicación del genoma seguida de dos divisiones celulares consecutivas. Durante la meiosis en Saccharomyces cerevisiae, se producen la formación del complejo sinaptonémico y la recombinación de los cromosomas homólogos, lo que contribuye a la correcta segregación de los cromosomas y promover la diversidad genética de los gametos.La regulación de la meiosis implica múltiples mecanismos, entre los cuales destaca la oscilación en los niveles de las ciclinas-CDK. Estos cambios en los niveles de ciclinas-CDK conducen a variaciones en la fosforilación de diversos sustratos, desencadenando importantes eventos celulares. Por ejemplo, durante la anafase I, la liberación de Cdc14 del nucleolo desencadena una disminución en los niveles de CDK, lo que conduce a la finalización de la primera división meiótica y el avance hacia la siguiente fase del proceso...

These changes in cyclin-CDK levels lead to variations in the phosphorylation of various substrates, triggering important cellular events. For example, during anaphase I, the release of Cdc14 from the nucleolus triggers a decrease in CDK levels, leading to the completion of the first meiotic division and progression to the next phase of the process...
