    GT for Biology P22

    I remember that in one of the parts, it was the tertiary structure, and i remember the functions of the first three parts. This is all i'm able to recall.

    So you're talking about that one. It's correct i think, however, i don't remember the question exactly.

    I don't remember the question exactly, But that part was asking whether the structure was quaternary or tertiary and it was tertiary since there was only one polypeptide chain. I don't think enzyme was anywhere there in the paper.

    No, there were two chains as far as i can recall (though not sure). But what else could be the function then? This was the only thing i found to be correct. What were the processes in the first question?

    The site where an antigen binds in the variable one. And enzyme binding on antibody ( i never read such thing). Flexibility is important for an antibody molecule as it can adjust to hold the antigen on it's variable region. Besides, this was the only function i came across and that's why i...

    It's gonna be really tough. As you have not even touched the extra one's, so, it's going to get very difficult for you later. You might face time management difficulties. It can affect the result of your compulsory subjects too, as it's going to divide your concentration and all. On the whole...

Cover each topic given in syllabus to its full. Since you have an year (or even less), so make sure you study each day and try to make...
