Regulation Definition and Examples - Biology Online Dictionary

Regulation of Biological Systems tutorials are focused on the modulation of biological systems from cell to population levels. The course starts with the principles of negative feedback control, and how it regulates blood sugar, water, and temperature in humans. It, then, culminates in the population regulation and ecosystem succession. Learn ...

22.1: Gene regulation: Introduction - Biology LibreTexts

CAUTION: Depending on your instructor, you may cover a few real biological examples of positive and negative regulatory mechanisms. These specific examples will use the common names of the transcription factors - since the the examples will typically be drawn from the bacterial literature, the names of the transcription factors may include the terms "repressor" or "activator".

What is regulation - Unacademy

Example of regulation in biology: Physiological process regulation Any process that alters the frequency, rate, or scope of a biological process is referred to as modulation. Controlling gene expression, protein modification, or contact with a protein or substrate molecule are just a few examples of how biological processes are regulated.

Gene Regulation: Definition, Steps, and Examples - ResearchTweet

Gene regulation is a mechanism that controls the genes by activating a few of them out of the many genes that are present in its genomes. Gene regulation is very much important as each cell in our body has a different set of genes, interestingly, all cells in our body have the same DNA, but these differ in their expression of the genes, causes variations among them and each of the cells has a ...

Biological regulation: controlling the system from within

Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second-order control, exerted over the core (constitutive ...

Regulation of Gene Expression: Negative and Positive Regulation

It consists of synthesis of specific RNAs, polypeptides, structural proteins, proteinaceous bio-chemicals or enzymes which control the structure or functioning of specific traits. 3. Gene regulation is the mechanism of switching off and switching on of the genes depending upon the requirement of the cells and the state of development.

Eukaryotic Gene Regulation – Mechanisms, Regulatory Elements

Eukaryotic gene regulation is a fundamental aspect of molecular biology that plays a critical role in the expression of genes within eukaryotic cells. This intricate system governs when, where, and how much specific genes are expressed, which is essential for the proper development and functioning of organisms, ranging from unicellular protozoa to complex multicellular organisms, including humans.

Regulation of gene expression - Wikipedia

Regulation of gene expression, or gene regulation, [1] includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental stimuli, or adapt to new food sources.
