Methods for Synchronizing Cells at Specific Stages of the Cell Cycle The protocols presented here describe procedures used to synchronize cells in various stages of the cell cycle (Fig. 8.3.1). Synchronization is particularly useful for investigating a particular cell cycle–regulated event or preparing cells for extraction of transient factors whose expression is dependent on cell cycle stage. Exponentially growing cultures are generally asynchronous; i.e.‚ each cell progresses through the cell

1.0 Introduction 1.1 Background of the Issue In recent years‚ the phrase ’stem cells’ has become a popular and widely published scientific topic. Debate and discussions about stem cells are everywhere‚ including magazines‚ television‚ etc. Basically‚ stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Commonly‚ stem cells come from two main sources: embryonic stem cells and adult stem cells (Crosta‚ 2008). 1.2 Current Situation Rates of chronic

Exam Review – January 2013 Diversity Unit - List taxonomic ranks in order. What is the significance of this order? Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ Species. Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example

have the remarkable potential to develop into many different cell types in the body. Stem cells are distinguished from other cell types by two important characteristics. First‚ they are unspecialised cells capable of renewing themselves through cell division‚ sometimes after long periods of inactivity. Second‚ under certain physiologic or experimental conditions‚ they can be induced to become tissue‚ or organ-specific‚ cells with special functions. In some organs‚ such as the gut and bone marrow‚ these

Deontology and Stem Cell Research Stem cell research is very controversial in today’s world. Although stem cell research has the potential for curing diseases and conditions‚ some people view stem cell research as unethical and immoral. People do not realize that there is hope for medical advancement today because medical specialists can use stem cell research to grow practically any cells needed for sick patients. Today‚ I am going to tell you what deontology is‚ how the school of thought views

Doctor- “A brain-eating amoeba” is just as horrific as it sounds‚ is a parasite that can enter the brain and lead to deadly inflammation of the brain. Naegleria fowleri makes its way into our body by entering the brain through the nose typically when someone goes underwater. It infects the brain‚ leading to meningitis‚ which eventually causes death. The infected person normally dies within a period of 2 weeks.“Naegleria Fowleri” is the genus and species name of the amoeboflagellate. This amoeba causes
