--Sadaf Masood 14:47, 20 August 2009 (EST) I have been presesnt in lab 1, 2 and 4!!!

--Sadaf Masood 13:13, 27 August 2009 (EST)Me here in lab 5!!

Week 5 Lab Present in lab 6!

1. Answer: What is Congenital Diaphragmatic Hernia and how does it affect the human lungs?

2. Answer: The diaphragm is the muscular sheet that separates the chest from the abdomen. A congenital diaphragmatic hernia occurs when the diaphragm does not form properly during pregnancy. A defect or hole in the diaphragm allows the intestine to push through the muscle, squashing the lungs, and preventing the lungs from developing properly.

Week 6 Present in lab 7!

1. Answer: Cleft Lip

2. Answer: Tubotympanic recess, tympanic cavity, mastoid antrum, eustachian tube

3. Answer: Neural crest cells- (melanocytes)

Week 7

Present in lab 8!

1. Answer: It is a multi-nucleated cell that comes from the differentiation of myoblasts and creates the mature muscle fibres.

2.(a)Answer: Muscle Atrophy would occur within the muscle

(b)Answer: There would be a conversion to slow twitch fibres within the muscles

Week 10

1. Answer: Muscle, Neural stem cells and Mesenchymal cells

2. Answer:

Viral vectors – viruses with the potential to affect the transcriptional profile of cells, sometimes inducing cell death or tumors.

Non viral- avoids viruses intergrating into the genome (corrected answer)

3. Answer: True

--Antonio Lee 15:18, 31 October 2009 (EST) 3/3 Correct (NB Q2 non-viral method does NOT use lenti-virus)
