| Q. |
A group of genes whose activity is coordinated by a DNA site is – |
| A. | operon |
| B. | cistron |
| C. | polysome |
| D. | polypeptide |
| Answer» A. operon | |
|
Explanation: The operon is defined as a group of genes whose activity is coordinated by a DNA site. An operon is a functioning unit of genomic DNA containing a cluster of genes under the control of a single promoter. The genes are transcribed together into an mRNA strand and either translated together in the cytoplasm, or undergo trans-splicing to create monocistronic mR-NAs that are translated separately. |
