Why is regulating transcription the main way that cells control gene expression? A. Because transcription is the last step in gene expression, stopping here ensures that the cell has a stockpile of
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.
Why is regulating transcription the main way that cells control gene expression?
| A. |
Because transcription is the last step in gene expression, stopping here ensures that the cell has a stockpile of proteins to prepare them from all unexpected environmental changes. |
|
| B. |
Because transcription involves interactions with DNA, preventing transcription reduces the changes of mutation in the cell’s genome. |
|
| C. |
Because transcription is the first step in gene expression, stopping at transcription reduces the amount of energy and |
|
| D. |
Because transcription is the shortest step in gene expression, preventing transcription has little effect on the rate of protein production. |
