diamong [38]
<span>DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a template for replication. Primers bind to the DNA and DNA polymerases add new nucleotide sequences in the 5′ to 3′ direction. This addition is continuous in the leading strand and fragmented in the lagging strand. Once elongation of the DNA strands is complete, the strands are checked for errors, repairs are made and telomere sequences are added to the ends of the DNA.</span>

Explanation:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.  

It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.

However, such mutant (X) communicates and expresses itself and she is hemophilic.

This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.
