What is the main function of the origin of replication?

Options

  1. ATo control the copy number of the linked DNA
  2. BTo start replication
  3. CTo eliminate nontransformants
  4. DTo permit the growth of transformants

Correct answer

B. To start replication

Step-by-step solution

This is a sequence from where replication starts and any piece of DNA when linked to this sequence can be made to replicate within the host cells . This sequence is also responsible for controlling the copy number of the linked DNA. So, if one wants to recover many copies of the target DNA it should be cloned in a vector whose origin support high copy number
