Chromosomes are comprised of nucleotides and nitrogen base pairs. The nucleotides make up the columns of the DNA structure, and are repeating sequences of a 5-carbon sugar and a phosphate.
The "rungs" of the DNA structure, similar to the rungs (steps) of a ladder, and made up of four variations of nitrogen base pairs.
A species that contains two copies of each chromosome is called diploid. Each pair of chromosomes, one from each parent, make up a diploid set in the organism.
A chromatid is one half of a duplicated chromosome, joined together by a centromere. Each chromatid contains identical genetic material and is essential for proper chromosome segregation during cell division.
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.
The two chemical components of chromosomes are DNA and proteins. Original researchers thought that protein was the genetic material because proteins had specific functions with great heterogeneity.
Chromatids are identical copies of DNA that are joined together at the centromere to form a chromosome. Each chromatid carries genetic information necessary for cell division. When a cell is ready to divide, the chromatids separate and are pulled to opposite ends of the cell.
Two chromatids connected at the centromere make up one chromosome.

Somatic cell chromosome is made of two identical chromatids
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.

There are two things that make up fermentation. The two things that make up fermentation are lactic acid and propionic acid.
A chromosome is formed from a single DNA molecule.
