AIMNET_LIFESCIENCE
Hey all Biotecnika Members
I am Richa Singh. As we all know Biotecnika is starting its online test series AIMNET from 1st august, 2010 and to register we are requierd to have 30BT points. Since we are preparing for CSIR NET, we usually come across some doubts, queries and facts. what i thought we can share these queries, or post questions here and score BT points. Post 3 questions daily from any subject (Biochem, Immuno, genetics etc) and score points. this will help in preparation and in a week you gonna have 42 points!!!
Cheers...
Update; Since this discussion thread had become very long so in order to make it easier to navigate we have disbaled the thread comments
Can anyone suggest me the book for preperation of NET exam
1. Which function is not related with Th1 cells?
a) IFN-gamma
b) induce phagocytosis
c) promoting antibody binding to soluble antigen
d) secretion of IL-2
2. Small amount of lethal mutation always tend to remain in population is due to
a) positive selection
b) negative selection
c) frequence dependant selection
d) mutation selection balance
3.In sandwitch ELISA the molecule captured is

1. A major functional difference between the succinyl CoA-synthetase of plant and animal mitochondria is that it
a) produces UTP in plant cell
b) produces ATP in plants and GTP in animals
c) does not produce ATP in plant cell
d) produces GTP in plants and ATP in animals
Great idea ! This way we can access so many questions. My suggestion is .. for every question, the owner of the question must provide the correct answer and make it CAPS or GREEN, whichever is easier, so that others can know what the correct answer is. I was seeing that most people are just writing a word for the answer and it doesn't make any sense.
Please provide the QUESTION as well as ANSWER :-))
Will be helpful.
