Gene expression noise refers to the variability in the level of gene expression among cells in a genetically identical population, which can arise from stochastic biochemical processes. This phenomenon can have significant implications for cellular function and phenotypic diversity, influencing processes such as development, adaptation, and disease progression.

Stochastic biochemical processes

Cellular function encompasses the myriad activities carried out by cells to maintain homeostasis, facilitate growth, and ensure survival. It involves complex interactions between cellular structures and biochemical pathways to perform tasks such as energy production, molecular transport, and signal transduction.

Cellular Function

Phenotypic diversity

Development refers to the process of growth, progress, or evolution in various contexts, such as personal, economic, or social domains. It involves the improvement of conditions, skills, or systems, often measured through indicators like quality of life, education, and economic prosperity.

Development

Adaptation is the process through which organisms or systems adjust to changes in their environment to improve survival and functioning. It involves both physical and behavioral changes that enhance the ability to cope with new conditions or challenges.

Adaptation

Disease progression refers to the sequence of events and changes in the body that occur as a disease develops and worsens over time. Understanding disease progression is crucial for predicting outcomes, planning treatments, and developing interventions to halt or reverse the disease's impact.
