The phrases or terms describe different fundamental processes of nucleic acids. classify each phrase or term as relating to replication

The replication of DNA occurs through the following phases - unwinding of strands, binding of RNA primers, elongation, removal of primers, DNA repair and termination of replication.

Explanation:

There are two types of nucleic acids one is RNA and the other is DNA. DNA makes a new copy by the process of DNA replication. The replication of DNA is semiconservative type.  

It consists of different steps. The first is an unwinding of the two strands of DNA. This occurs by helicase enzyme which acts like a scissor. The point where this enzyme acts and strat the unwinding is called the origin of replication.

The second step is the synthesis of an RNA primer at the point of origin. It is formed from the DNA template. This RNA primer helps to synthesize new DNA strands and elongates the DNA. This process is called elongation. It forms two strands- leading and lagging strands.

The lagging strand consists of many RNA primers that should be removed.  

The RNA primers are removed by DNA polymerase I and it helps in adding complementary strands of DNA. As a result, one new DNA forms from the older one. The final step is DNA repair, which has done by enzyme nuclease.

The enzyme nuclease removes the wrong nucleotides and DNA polymerase fills the space with correct complementary nucleotide.
