You are studying how gene expression is regulated in the cell. For gene z, you find that while there are high levels of mRNA in the cell, there are low levels of the protein encoded by gene z. Describe a regulatory mechanism that could explain this finding that occurs after translation.
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
![**Topic: Post-Translational Regulation in Gene Expression**
You are studying how gene expression is regulated in the cell. For gene z, you find that while there are high levels of mRNA in the cell, there are low levels of the protein encoded by gene z. Describe a regulatory mechanism that could explain this finding that occurs after translation.
**Explanation:**
This situation may be explained by post-translational modifications or regulatory mechanisms that reduce protein stability or promote protein degradation. For instance, the protein encoded by gene z could be rapidly targeted for degradation by the ubiquitin-proteasome pathway. Alternatively, modifications such as phosphorylation could make the protein more susceptible to degradation or sequestered in an inactive form. Understanding these mechanisms can provide insights into how gene expression is finely controlled beyond the level of mRNA production.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc0ff916c-a9ca-4791-8d5c-b57cb6fa675f%2Fe2e65e62-d5b6-438a-99f3-90f8a5f9fdd8%2Fmfk3imr_processed.png&w=3840&q=75)
