MEIOSIS We study Gametes through a Karyotype Each pair is called a homologous pair Diploid= 23 pairs of chromosomes and 46 total chromosomes (2n) Haploid= 23 individual pairs Mitosis- makes body cells‚ or asexual reproduction like cloning Meiosis- makes sex cells Crossing Over- Occurs in Prohpase I - each group of 4 chromatids are called a tetrad. Individual chromatids may wrap around eachother and pieces may break off and reattach to other chromatids. Genes on chromosomes may change places

Therapeutic cloning. In order to understand Therapeutic cloning is important to define what stem cells are? Stem cells have the capacity to develop in any type of cell of the human body. For scientist this is a great advancement because stem cells can be used to reproduce and create organs to help people who are in need of an organ transplant or are undergoing terminal diseases. The opposition to therapeutic cloning argues that embryos should not be created for the sole purpose of being used as

Animals which are endangered destroy due to not variety.I mean that species which can survive have common gene in their DNA. Genetic disorders can be transferred passing down and any disorder in DNA can easily spread

by two scientists. They are Sir John B. Gurdon from United Kingdom and Prof. Shina Yamanaka from Japan. They both contribute to develop human cell studying. Official Nobel Prize announced that the Prize motivation is "for the discovery that mature cells can be reprogrammed to become pluripotent". They discover that mature cells can be converted to stem cells. Sir John B. Gurdon was born in Dippenhall in 1933. He is a British developmental biologist‚ which is the discipline of organism grow and

President Barack Obama’s removal of the Bush administration’s restrictions on federal funds for stem cell research. He explains that is important to understand that the research is a delicate process‚ and that is has the possibility to provide great benefits to medicine‚ such as the regeneration of cells in the human body. He also says he will not allow any federal funds for human cloning; stating that it is wrong and is not social acceptable. President

fundamentals of science. Title An investigation of an onion cell using a light microscope. Aim: The aim of this investigation is to identify the cells within an onion skin using a light microscope. An onion cell is a plant cell which through the light microscope‚ it should outline the cell wall‚ cell membrane and the nucleus. Introduction: Plant cells have a cell wall and cell membrane which animal cells do not have. The cell wall provides support and is relatively rigid‚ which consists of

and breast cancer stem cells Within a tumor exists a subpopulation of cells that present less abnormal characteristics; however‚ there exists another type that hold the potential to recreate and expand tumor mass. The latter share similar characteristics to normal stem cells‚ which are the unlimited ability to self-renew and the ability to maintain undifferentiated. Over the course of time‚ these cells will differentiate into tumor stem cells (TSC) or tumor-initiating cells with stem-like properties
