Theoretically because the same nitrogen bases match either side of the helix, and since there is only one base to match each base, each of the replicated helices should come out identically.
However, in practice this doesn't perform perfectly. Every replication has its share of mutations and where they occur is completely random. While the cell takes every precaution to prevent as much mutations as possible, some do go unnoticed. In reality, the two helices are closer to being 99.9999% identical. Some have put the accuracy of DNA replication to 1 mistake per billion nucleotides added.
Sister chromatids - two copies of the same DNA joined at the centromere.
In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
The plural of helix is helices.
During DNA replication, each double helix produced consists of one original parental strand and one newly synthesized daughter strand. The parental strand serves as a template for the synthesis of the complementary daughter strand, resulting in two identical double helices.
Helix is singular. Helices is plural.

After DNA replication, the two DNA double helices have the same composition as the original DNA molecule. Each new double helix consists of one original strand (the template strand) and one newly synthesized strand (the complementary strand). This ensures that the genetic information is faithfully preserved and passed on to the daughter cells.
no both the double helices aren't the same. the sequences(bases) that are part of one of the helix is sequence complementary to the other strand of DNA.structurally they form the helical pattern, the sequence information is absolutely different.this itself determines the specificity,
DNA replication of one helix of DNA results in two identical helices. If the original DNA helix is calledthe "parental" DNA, the two resulting helices can be called "daughter" helices. Each of these two daughter helices is a nearly exact copy of the parental helix (it is not 100% the same due to mutations).DNA creates "daughters" by using the parental strands of DNA as a template or guide. Each newly synthesized strand of DNA (daughter strand) is made by the addition of a nucleotide that is complementary to the parent strand of DNA. In this way, DNA replication is semi-conservative, meaning that one parent strand is always passed on to the daughter helix of DNA.
The coils of DNA are called double helix. This structure consists of two intertwined strands of nucleotides forming a twisted ladder shape.
At the start of the G1 phase, there is one double helix of DNA present in the cell. By the start of the G2 phase, the DNA has replicated to form two double helices, ready for cell division.
A collagen helix is less compact (because it goes into triple helices), and it is a left-handed helix. An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
