PGD – Pre-implantation Genetic Diagnosis. IVF is known as in vitro fertilisation. This procedure is done by removing an egg from a female, and a sperm cell from the male and combining the egg and sperm in a test tube. These two then form together and create a zygote, which then begins separating into and forming an embryo . PGD, is the pre-implantation genetic diagnosis. It is known as the pre testing of pre-implanted embryos for genetic disorders. This operation has been put into place for couples

fundamental basis for the genetic code universally deciphered by living cells. You will produce sequences of ribonucleotides that will be translated into protein to simulate the landmark experiments involving cell-free extracts that were essential for interpreting and understanding the genetic code. A major step forward in figuring out the code was the discovery by Nirenberg in 1961 that a cell-free extract made from E. coli cells could translate RNA added to the extract into proteins. The composition

COMMENTS ON CENTRAL NERVOUS SYSTEM AND RADIOLOGICAL ANATOMY Radiological Anatomy Radiological anatomy is a medical specialty that employs the use of imaging to both diagnose and treat disease visualised within the human body. It explores various tissue densities to be able to determine structures. It could either be invasive or non-invasive. Radiologists use an array of imaging techniques which include: • Conventional radiography (X-ray) • Ultrasound • Computerized Tomography

thought that at the time of infection with chickenpox the virus migrates from the skin to the sensory ganglia via the axons of peripheral nerves and remains dormant in the ganglia, usually for many years. Activation of the virus occurs when the subject’s cell immunity is reduced. The activated virus travels along the sensory nerve

Final Exam Study Guide Important to Know the function of anterior and posterior pituitary gland. Anterior Pituitary Gland: (Adenohypophysis) The anterior pituitary gland regulates several physiological processes including stress, growth, reproduction and lactation (Adrenal, liver, bone, thryroid and gonads). -It is regulated by negative feedback and the hypothalamus.
