Tutorial examines how a cell divides to make two genetically identical cells and explores the four basic phases: prophase, metaphase, anaphase, and telophase.

Through full-color images and concise information, learn about adenosine triphosphate, or ATP, the molecular unit of energy currency of cells.

This informative resource features an overview of genetic material: DNA, chromosomes, genomes, homologous chromosomes, sister chromatids, and haploid/diploid.

Endocytosis enables cells to absorb extracellular nutrients that are needed for their survival. In receptor-mediated endocytosis, a protein receptor on the cell membrane binds to a nutrient molecule and facilitates its absorption through...
