Answer:
The 5' and 3' polarity restriction
Explanation:
Discontinuous replication is when synthesis of new DNA molecule takes place as a series of short fragments that will subsequently be joined together.
These fragments are called the Okazaki fragments.
DNA synthesis takes place from 3' to 5' end. However due to 5' and 3' polarity. The replication has to be discontinuous due to the synthesis happening backwards and okazaki fragments being formed.
The answer would be TIA
Transient Ischemic Attack or TIA is a <span>sudden deficient supply of blood to the brain lasting a short time. This will cause the loss or reduction of function of the affected brain area. The symptoms should disappear <24 hours to have it diagnosed as TIA. If the symptoms persist >24 hours, the diagnosis would be RIND or stroke.</span>
The theory of evolution provides a number of insights:
-it tells us how the species are related
-it tells us how the species and populations react to the changes in their environment
With this knowledge, the scientists can predict how the species will react to the potential changes and support the positive changes (provide a good environment for the animals for example) <span />
