Review your understanding of chromosomes and genes in this free article aligned to NGSS standards. Key points: All organisms inherit traits, or observable characteristics, from their parents.Human Chromosomes. Human cells normally have two sets of chromosomes, one set inherited from each parent. There are 23 chromosomes in each set, for a total of 46 chromosomes per cell. Each chromosome in one set is matched by a chromosome of the same type in the other set, so there are actually 23 pairs of chromosomes per cell.Description. This animation shows how DNA molecules are packed up into chromosomes. DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin.We are all familiar with the images of DNA molecules as thread-like strands of double helix.

Dear Lifehacker,

A cell’s DNA, packaged as a double-stranded DNA molecule, is called its genome. In prokaryotes, the genome is composed of a single, double-stranded DNA molecule in the form of a loop or circle (Figure 12.2.1 12.2. 1 ). The region in the cell containing this genetic material is called a nucleoid (remember that prokaryotes do not have a ...
