In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear ...
These cells and others in the body are exact ... The dark bands indicate areas where the structure of the chromosome is dense. Each of the 23 chromosome types has a unique banding pattern.
The diagram shows the relationship between the cell, its nucleus, the chromosomes in the nucleus, and genes. The order that these bases are found in the genes determines the order of the amino ...
