Nucleus Contains Genetic Information
(Note: This post has 4 comics!)

The nucleus*  is the cell’s “command center”, and it is usually located near the center of a cell.  (*Plural for nucleus = nuclei)

The nuclear membrane makes up the surface of a nucleus, and it consists of phospholipid molecules, which is also the same substance that makes up the cellular membrane.

Inside the nucleus, you will find the cell’s genetic material–DNA.  Because DNA regulates all cell’s activities, nucleus is called the “command center” of a cell.  It is also
for this SAME REASON that nucleus is located near the center of a cell where it is well-protected.

HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

MS-LS1-1. Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.

MS-LS1-2. Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.

MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

Additional Information


Short for “information”.

Genetic Information

Also called “genetic materials”.  They are the DNA molecules that contain information on the organism’s traits (characteristics and qualities), and they can be passed down form parents to offspring.  Most genetic materials consist of DNA molecules, while some genetic materials consist of RNA molecules


This word is short for “deoxyribonucleic acid”, and it is the molecule that makes up organisms’ genetic materials.  Its slight variant “RNA” (ribonucleic acid) is sometimes used as genetic materials for more primitive/simple organisms.
