Reproduction
Growth and Cell Reproduction Growth is a feature shared by all living organisms. You began as a single cell. That cell rapidly split into two. Two cells grew into four, and four grew into eight. You eventually developed into a multibillion-cell creature. As you develop, your cells divide to produce more and more cells. Your cells also divide to replace dead cells or to repair damaged tissues. Each new cell has an exact duplicate of the DNA contained in every cell in your body. How can cells divide to produce precise duplicates of themselves? What exactly is cell division? Cell division is the process through which one cell divides into two daughter cells. Each daughter cell carries an identical copy of the parent cell's DNA. What exactly are chromosomes? Prokaryotic cells are typically smaller and less complicated than eukaryotic ones. A eukaryotic cell's DNA is located in the nucleus. This DNA is arranged into structures known as chromosomes. A chromosome is a DNA and protein...
