In Eukaryotes, the DNA replication can start at several sites or places in the DNA molecule or DNA strand. The only important factor for DNA replication to start is that it starts at replication fork.
The replication of DNA is semi-conservative in nature because each strand acts as a template for synthesizing a new complementary strand of the double helix.
The new DNA is made with the help of the enzyme DNA polymerase which requires a primer for starting the DNA synthesis.
Replication occurs only at specific regions of DNA known as origin of replication and these are short sequences of nucleotides which are recognized by the enzyme for the replication.
The special enzymes or proteins recognize the specific sites and then binds to them. After binding, the DNA is opened up forming the replication forks which are two Y- shaped structures.

Answer:
Deleterious alleles appear sporadically in a population
Explanation:
A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.
Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.
