Practicing Success
If a scientist wants to recover many copies of the target DNA through recombinant DNA technology, what augmentation need to be done in cloning vector? |
Reduce cloning sites add origin of replication (ori) that support high copy number add more selectable marker add more cloning sites |
add origin of replication (ori) that support high copy number |
The correct answer is Option (2) – add origin of replication (ori) that support high copy number The origin of replication (ori) is a crucial element in a vector used in genetic engineering. It serves two essential functions:
By choosing an appropriate vector with the right ori sequence, scientists can control the number of copies of the target DNA they want to recover. This feature is essential when one needs a high yield of the recombinant DNA for further analysis or experimentation. |
