Lab 1 Online Assessment

1. Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.

An American doctor, John Rock was the first to extract an intact fertilised egg, which is an important technique used to complete IVF today. Robert Edwards was awarded the 2010 nobel prize for his success in replicating conception through IVF.

2. Identify a recent paper on fertilisation and describe its key findings.

Pregnancy after Age 50: Defining Risks for Mother and Child. Kort DH, Gosselin J, Choi JM, Thornton MH, Cleary-Goldman J, Sauer MV. Am J Perinatol. 2011 Aug 1.

In 2011, a study was performed on women over the age of 50 undergoing IVF treatment and its associated risks. The study shows that with increased maternal age, the risks associated with birth defects and maternal complications is greatly increased.

3. Identify 2 congenital anomalies.

Cleft Palate and congenital hip dysplasia

Lab 2 Online Assessment

1.Identify the ZP protein that spermatozoa binds and how is this changed (altered) after fertilization.

ZP3 is the only glycoprotein that functions as a sperm receptor. It is known that ZP3 protein, in the zona pellucida, binds sperm and stimulates acrosomal exocytosis, enabling the process of zonal penetration (Clark, GF). In order to prevent polyspermy, it is believed that certain enzymes break down the zona pellucida and hence inactivating the ZP3 glycoprotein.

Lab 3 Online Assessment

1. What is the maternal dietary requirement for late neural development? Research has shown that folate is an important dietary requirement for the closure of the neural tube in foetal development. Incomplete or non closure may result in spina bifida (which occurs at the caudal end) or anancephaly (occurs at the cranial end).


2. Upload a picture relating to you group project. Add to both the Group discussion and your online assessment page. Image must be renamed appropriately, citation on "Summary" window with link to original paper and copyright information. As outlined in the Practical class tutorial.
