Class notes BIO1130 - BIO1130 Organismal Biology (BIO1130)
In the context of cell signaling, Active Ras refers to the activated form of the Ras protein, a pivotal molecular switch that regulates various cellular processes. Ras activation is triggered by binding of GTP (guanosine triphosphate), leading to a cascade of intracellular events. Active Ras plays a crucial role in transducing external signals, such as growth factors, into intracellular responses, including cell proliferation and differentiation. Dysregulation of Ras signaling is implicated in n...

Histone acetylation relaxes chromatin, promoting transcription, whereas DNA methylation often leads to gene silencing. This regulatory complexity extends to development, diseases like cancer, and potential therapeutic strategies, emphasizing the interconnectedness of these molecular phenomena in shaping cellular life.

Active Ras, a pivotal molecular switch, plays a central role in cellular signaling by transducing external cues into intracellular responses. Triggered by GTP binding, active Ras influences critical processes such as cell proliferation and differentiation. In parallel, the facilitated absorption of glucose, orchestrated by specific transporters, fuels essential cellular functions through glycolysis, yielding ATP as an energy source. Meanwhile, the intricate world of epigenetics is governed by ac...
