What is a chromatid?
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.
How many sister chromatids are there in a duplicated chromosomes?
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.
How are chromatid and a duplicated chromosome are related?
A chromatid is one of the two identical copies of a chromosome that are joined at the centromere. When a chromosome is duplicated during DNA replication, each half of the chromosome becomes a chromatid. Therefore, a duplicated chromosome consists of two sister chromatids.
What is the Primary molecular composition of chromatids--in addition to protein?
The primary molecular composition of chromatids, in addition to proteins, is DNA. Chromatids are composed of tightly coiled DNA molecules that contain genetic information necessary for cell division and replication. The DNA molecule is wrapped around histone proteins to form nucleosomes, which further organize the genetic material within the chromatid.
What are strands of DNA called?
During Prophase I, DNA is exchanged between homologous chromosomes.Meiosis begins when a cell's chromosomes are duplicated by a round of DNA replication. The strand holding the DNA is the homologs and has an exact copy know as a sister chromatid.
What is a chromatid made of?
DNA
What is each rod in a cells DNA called?
I think it's a chromatid.
What molecule makes up a chromatid?
Chromatin

What are the two strands of a double stranded chromosome called?
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.
What is one member of the chromosome do?
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.
How many copies of a DNA molecule results of two replications of a single DNA molecule?
Four.

How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
