Answer:
Both leading and lagging strands
Explanation:
DNA replication is the enzyme of DNA replication that forms new DNA strands. However, the enzyme cannot start the process of synthesis of new DNA strands by itself but needs small primers. Primers are the small RNA sequences synthesized by RNA primase on both leading and lagging strands.
These primers are elongated by DNA polymerase by the addition of deoxyribonucleotides according to the sequence of the template strand. Since DNA replication on both lagging and leading strand is carried out by DNA polymerase, RNA primers are present on both lagging and leading strands.

I hope this is correct, if it isn't then feel free to let me know and I will correct it. I'm sorry in advance if it is incorrect.
 
        
             
        
        
        
<span>the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction. </span>
        
             
        
        
        
Open-mindedness is needed for the emerging scientific ideas to be accepted (or : to not be rejected without consideration). 
Additionally, open-mindedness as a attitude often leads to new scientific ideas emerging: it means that people are more comfortable to try out new things and to test new hypotheses.  
        
             
        
        
        
B. a volcano that erupts in blasts of the pyroclastic matter. D. would be wrong because the shield volcano can have explosive eruptions but they are generally quiet
