Question

The cell is capable of regulating gene expression in a variety of situations and environments. valid reasons for a cell to regulate gene expression include its ability to: make additional cells of the same type in response to a demand.

O false synthesize enzymes to metabolize a particular nutrient.
O true keep a gene product available under all conditions. false execute a specific program of development (e.g. to become a blood cell or immune cell).
O false stop synthesis of a cellular component when there is enough available in the cell.
O true synthesize mrna for every gene in the genome at all times.

Answer 1

Cells regulate gene expression to respond to environmental signals, conserve resources, and execute development programs. Gene expression involves turning on genes to produce RNA and proteins when they are needed, and not all genes are expressed constantly to avoid inefficiency.

Step-by-step explanation:

The cell is capable of regulating gene expression to respond to various needs and environmental conditions. For a cell to function properly, it is critical that proteins be synthesized only when needed. Cells regulate gene expression to save energy and space, responding to environmental signals, ensuring proteins like enzymes are produced to metabolize specific nutrients, and executing developmental programs, such as differentiation into specific cell types like blood or immune cells. Additionally, they stop the synthesis of cellular components to prevent waste when there is no demand.

The regulation of gene expression in a cell allows it to make additional cells of the same type when required, synthesize enzymes for particular nutrients, conserve resources by not producing gene products unnecessarily, execute specific developmental programs, and prevent the overproduction of cellular components. However, cells do not synthesize mRNA for every gene in the genome at all times, as this would be an inefficient use of resources.
