Each chromosome is originally made of one DNA molecule.
A chromatid is one half of a chromosome at a stage of the cell cycle when the chromosome contains two molecules of DNA.A chromatid is like a twin; you can only use the term when there are two of them!Before DNA replicates, each chromosome has only one molecule of DNA. After replication of the DNA, there are two DNA molecules in each chromosome. These become visible under a light microscope when the chromosomes condense during prophase of the next division.Each chromosome then looks like an X. The left side of the X contains one DNA molecule (together with proteins) and the right side contains the other. Each half of the chromosome is a chromatid. At anaphase of the division, the two chromatids are pulled apart. From then on they are no longer referred to as chromatids, but as daughter-chromosomes.
A typical DNA molecule consists of two strands.

There are two sister chromatids in a duplicated chromosome. Each sister chromatid is an identical copy resulting from DNA replication during the S phase of the cell cycle.
Chromosomes and chromatids are related in that one is the duplicate of another. A chromatid comes about when chromosomes are duplicated. It holds replicated DNA of every single chromosome that is joined.

I think it's a chromatid.
Chromatin
The two strands of a double-stranded chromosome are called chromatids. Each chromatid contains a single DNA molecule that is duplicated and bound to its sister chromatid at the centromere.

One member of a chromosome is a single DNA molecule containing many genes. This DNA molecule is tightly coiled around histone proteins to form a compact structure. Chromosomes are found in the nucleus of eukaryotic cells and carry genetic information that determines an organism's traits.
