One of the nuclear bodies that carries hereditary factors in cells. There are 46 in humans.
Long pieces of DNA found in the center (nucleus) of cells.
Part of a cell that contains genetic information. Except for sperm and eggs, all human cells contain 46 chromosomes.
Minute bodies in the cell nucleus that bear genetic information.
Microscopic, intranuclear structures that carry the genes. The normal human cell contains 46 chromosomes, consisting of 23 pairs of chromosomes—22 pairs of autosomes and 1 pair of sex chromosomes.
Collection of genes packaged with histone proteins found in the nucleus of cells; humans have 23 pairs.
Discrete units of the genome carrying many genes, consisting of (histone) proteins and a very long molecule of DNA. Found in the nucleus of every plant and animal cell.
In human cells, a linear structure in the nucleus composed of DNA and proteins and bearing part of the genetic information of the cell. Each human cell (except for egg or sperm cells) has 46 chromosomes, occurring in 23 pairs.
The hereditary unit that consists of the genes and is the determiner of genetic makeup.
