Re: BIOLOGY 9700 Problems with Amino acids, help URGENTLY ne 2000 is for 2 strands.For 1 strand it'll be 1000. U take it to 1 strand coz they say itz beeen transcribed and translated where only 1 mrna strand undergoes this. -
Biology MCQ thread..!!
As for the 18th one i guess the ans is A.Each Trna consists of 1 amino acid and in this case there asking the MINIMUM no of amino acids req for 4 diff kinds, so it has to be 4.

Physics MCQs thread.
I guess D can be correct, coz Force applied is in the direction of (X apllyin a force on Y). In this case the only force applied by Y on X can be the reaction force (cz dis is bckward) which is the force applied by X on y. Ur MS is correct it seems.... Correct me if im wrong... -
