How many rounds of replication does it take for an incorporation error to be established as a base pair change?
iris [78.8K]

Answer:

Just one round without DNA repair

Explanation:

When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error

Select the correct answer. An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left.
lana [24]

Answer:The net force is the sum of all the forces acted upon an object. The direction of force depends on which side you are taking as a positive and negative force. If the force of 22 newtons is positive and the force of 13 newtons is negative, they are actng on the object on different directions, thus in order to get the net force, we just sum them up.

newtons

The net force is +9 Newtons.
