Why is gene expression regulated in prokaryotic cells quizlet?
Why is gene expression regulated in prokaryotic cells? Because it allows prokaryotic cells to better respond to stimuli and to conserve energy and materials.
Is gene expression regulated in prokaryotic cells?
Prokaryotes regulate gene expression by controlling the amount of transcription, whereas eukaryotic control is much more complex.
Why is it important that gene expression is regulated?
Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.
Why regulation of gene expression in eukaryotes is more complex than prokaryotes?
Eukaryotic gene expression is more complex than prokaryotic gene expression because the processes of transcription and translation are physically separated. Unlike prokaryotic cells, eukaryotic cells can regulate gene expression at many different levels.
How genes are regulated in prokaryotes?
The DNA of prokaryotes is organized into a circular chromosome, supercoiled within the nucleoid region of the cell cytoplasm. Both repressors and activators regulate gene expression by binding to specific DNA sites adjacent to the genes they control.
How is gene expression regulated?
Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.
How does gene expression differ in eukaryotes and prokaryotes?
Prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a defined nucleus; thus, the DNA is freely located within the cytoplasm. Eukaryotic gene expression occurs in both the nucleus (transcription) and cytoplasm (translation).
Why is gene expression regulated quizlet?
Why do we regulate gene expression (two reasons)? We regulate gene expression because transcription and translation take lots of energy so we need it. And it would be a waste of energy to make all proteins in all cells.
How does gene regulation differ in prokaryotes and eukaryotes?
Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm.
