Nucleic Acid Polymerization

Nucleic acids are the vital genetic blueprint, messengers and builders of the cellular world. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the genetic material of cells. Prior to cell division, a new copy of the DNA genome must be…

Plant Cell Walls

What differentiates plant cells from animal cells is that plant cells have a cell wall outside their plasma membrane. The cell wall protects plant cells and imparts stiffness to the plant, allowing it to grow tall. The composition of plant…

Eukaryotic Cell Structure Function

Eukaryotic cells possess several critical differences from prokaryotic cells, including a nucleus and other membrane-bound organelles. Here is a summery of some of the defining characteristics of the cell of eukaryotes (plants, animals, fungi and protists). * Two Basic Types…

Stages of Mitosis

Your body’s cells obviously can’t live on forever, so they need to reproduce in order to keep your body and mind functioning properly. So how does your body replenish its cells? The answer is this: by an asexual reproduction process…

Eukaryotic Membrane System

The cell’s endomembrane system consists of the rough and smooth ER, Golgi apparatus, vesicles and plasma membrane, all working together to transport cellular materials. * Eukaryotic Cells * Eukaryotes are organisms composed of cells that have their genetic material encased…
