Daughter moloqules are newer than DNA moloqules
The two double helix molecules that result after replication are known as "a Pair of Daughter Strands"; each residing comfortably within it's own 'daughter Cell' nucleus.
In the conservative model of DNA replication, the parental DNA molecule remains intact and serves as a template for the synthesis of a completely new daughter DNA molecule. The resulting progeny DNA molecules, therefore, consist of one entirely old parental strand and one entirely new daughter strand.
The term 'daughter' is mostly used in molecular/cell biology to refer to mitosis/meiosis processes/components. In organic chemistry it would refer to the molecules that are produced from a reaction that breaks down a large molecule to yield smaller (although still relatively big) molecules. A good example could be the breaking of a polysaccharide in the middle of the polymer, yielding two smaller (although still quite big) oligosaccharides :)

The DNA of yellow perch does not differ from human DNA except in the sequences of the bases.

Its false... :P
In mitosis, DNA replication occurs once, resulting in two identical daughter cells. In meiosis, DNA replication occurs twice, resulting in four genetically diverse daughter cells.

When DNA is duplicated during mitosis, the cell undergoes a process called DNA replication where the DNA molecule creates an exact copy of itself. This ensures that each daughter cell receives a complete set of genetic information. The duplicated DNA molecules are then separated into the daughter cells during cell division.

DNA replication is said to be 'semi-conservative' because the two new daughter DNA molecules are "Half old" and "Half new". Half the original DNA molecule is saved, or conserved in the daughter molecules.
Generally the DNA molecule is double stranded to RNA's single strand. The RNA molecule uses uracil as a base while the DNA molecule uses thymine. RNA has catabolic properties that allow it to act in things such a ribosomes and tRNA. DNA is just a carrier of the genetic information.

During cell division, the DNA replicates itself to ensure each daughter cell receives a complete set of genetic information. The decrease in DNA mass occurs because the replicated DNA molecules are physically separated and distributed to the daughter cells.
