During DNA replication, a chromosome becomes two strands through a process called semi-conservative replication. The double helix structure of the DNA molecule unwinds with the help of enzymes, such as helicase, creating two separate strands. Each original strand serves as a template for the synthesis of a complementary new strand, resulting in two identical DNA molecules, each with one original strand and one newly synthesized strand.
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
Daughter Chromosomes
The chromatin in the cell becomes chromosomes in prophase, the first stage of mitosis. The chromatin coils tightly together to form into separate chromosome strands during this phase.
One of the two strands of a chromosome that becomes visible during meiosis or mitosis is known as the chromatid. Each chromatid is an exact copy of the other, formed during DNA replication in the interphase preceding cell division.

Daughter Chromosomes
The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.
every and any DNA strand can constitue to a chromosome :)

You can tell a chromosome has doubled because of the DNA's strands. They coil very tightly.
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
Chromatid
Each chromosome has a single strand of DNA.
These strands are called spindle fibers. Each replicating chromosome lines up vertically on a spindle fiber during metaphase. During anaphase, the fibers pull the replicating chromosomes apart (leaving one chromosome to go to either end of the cell).
