Running Head: Environmental Problems in Prenatal Development Environmental Problems in Prenatal Development Abstract For my research topic‚ I chose environmental problems in prenatal development. I chose this topic because I have a great interest in prenatal development and the care the mother provides that will negatively affect the fetus while it is still developing. Learning about the problems that occur will be an enormous advantage with my future career in nursing. Throughout my

Elizabeth Terry Biology 101-06 MWF at 3:00 November 14‚ 2011 Research paper DOWN SYNDROME Down syndrome is the most common cause of mental retardation Down syndrome is the most common cause of mental retardation. It is caused by the presence of an extra chromosome. Chromosomes contain sequences of DNA called genes that represent the genetic information that exists within a cell. Twenty-three distinctive pairs of chromosomes which is 46 in total. They are located within the nucleus

Chapter 12 Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin‚ these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin. Cyclin levels rise during the S and G2 phases then fall abruptly in the M phase

Kishore Introduction Some of the worst gender ratios‚ indicating gross violation of women’s rights‚ are found in South and East Asian countries such as India and China. The determination of the sex of the foetus by ultrasound scanning‚ amniocentesis‚ and in vitro fertilization has aggravated this situation

Two types of molar growth can be identified by chromosome analysis. With a complete mole‚ all trophoblastic villi swell and become cystic. If an embryo forms‚ it dies early at only 1 to 2 mm in size‚ with no fetal blood present in the villi. On chromosomal analysis‚ although the karyotype is a normal 46XX or 46XY‚ this chromosome component was contributed only by the father or an “empty ovum” was fertilized and the chromosome material was duplicated. (Pillitteri‚ 2010) With a partial mole

DNA SPOOLING ISOLATION OF DNA FROM ONION INTRODUCTION This project will demonstrate several basic steps required for isolation of chromosomal DNA from cells. To extract the chromosomal DNA‚ both the cell membrane and the nuclear membrane must be broken open. This is accomplished by disrupting the membranes with a solution of detergent and salt‚creating a cell homogenate. Once the DNA is released from the nucleus‚ it must be protected from nucleases‚ enzymes which will degrade the DNA. Keeping
