The process of turning off and on of genes is known as gene regulation.
Explanation:
When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.
The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.
Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.
A hypothesis is an educated guess. This is part of the scientific method developed in science to explain natural phenomena in the environment. Usually scientists use the hypothesis in their controlled experiments.
Whether it is a fact or not scientists use the hypothesis as a basis or a starting point for further explanations. This is known as the scientific hypothesis. When an educated guess yields the same results over time, the answer is called a theory. Something that is widely accepted but still needs to be proven and investigated further.
