Step-by-step explanation:
"BioInteractive" is a website created by the Howard Hughes Medical Institute that provides resources for teaching and learning about biology. One of the topics covered on the site is the eukaryotic cell cycle and cancer.
The eukaryotic cell cycle is the series of events that occur in a eukaryotic cell leading to its division and duplication of its DNA to produce two daughter cells. It is divided into four phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). During the G1 phase, the cell grows and carries out its normal functions. In the S phase, the cell duplicates its DNA. During the G2 phase, the cell prepares for cell division by synthesizing the proteins and organelles needed for mitosis. Finally, during the M phase, the cell divides into two daughter cells.
Cancer is a disease that results from the uncontrolled growth and division of cells. It is caused by mutations in genes that regulate the cell cycle and DNA repair. These mutations can cause cells to divide uncontrollably, leading to the formation of a tumor. If the tumor is malignant, the cancer cells can spread to other parts of the body and form new tumors, a process known as metastasis.
The "BioInteractive" website provides a range of resources for teaching and learning about the eukaryotic cell cycle and cancer, including videos, animations, interactive tutorials, and lesson plans. These resources can help students to understand the complex mechanisms that regulate the cell cycle and the genetic and environmental factors that can cause cancer.
