Process Of Meiosis Essay, Research Paper Meiosis is the reproduction of sex or germ cells in which there are two divisions required to complete the process. They are called meiosis I and meiosis II. In meiosis I, members of homologous pairs of chromosomes divide into two complete sets. There are four stages: prophase I, metaphase I, anaphase I, and telophase I.. -Prophase I is the first phase in meiosis I.

Cell Theory Essay, Research Paper History of the Cell Theory: Cells, the make-up of all living things. Some cell are complete organisms, such as unicellular bacteria and protozoa. Other types of cells are called multicellular, such as nerve cells and muscle cells. Withen the cell is genetic material, Deoxyribonucleic Acid (DNA) containing coded instructions for the behavior and reproduction of the cell.

Cloning Essay, Research Paper Cloning Cloning is the production of duplicate copies of genetic material, cells, or entire multicellular living organisms. The copies are referred to as clones. Cloning occurs naturally and is also engineered by human beings. The possibility that people might be cloned from the cells of a single adult human being had long been a subject primarily of fantasy and science fiction but became very definite at the end of the 20th century.

Virii Essay, Research Paper Viruses are not truly alive. They are much smaller and less complex than cells. Most viruses multiply exclusively inside living host cells. Viruses

The War on Cancer Cancer is a genetic disease caused by mutations in proto-oncogenes and tumor-repressor gene, the genes that control cell division. A mutation in proto-oncogenes increases cell division, while in the tumor-repressor gene inhibits cell division. A mutation in either of these can cause a cell to divide rapidly.

CELL STRUCTURE AND FUNCTION All living things are made of the same basic building blocks, cells. A human is made of 65 trillion cells. Cells are everywhere, on you skin, in your blood, and even on your tongue. In fact, your blood is clear but red blood cells are what make your blood red. Most living things are made up of many cells but some are made of only one cell, like amebas, paramecium, fungi, protists, monerans, and bacteria.

Blood Essay, Research Paper The average adult body contains about 10 to 12 pints of blood. Your body continuously replaces its red blood cells, making new ones with iron salvaged from old ones that have died. Blood transports nutrients and defensive antibodies, cells, and clotting factors.

Biology Of Cancer Essay, Research Paper Cells inside of our body are under strict genetic control. If the genes controlling our cells become mutated, the cells can become disorganized by losing their function and dividing abnormally at less restraint than their neighboring normal cells. This activity causes the cells to fail to fully mature.Within our cells, we have regulatory proteins that perforn such functions as correcting damaged genes.
