Yeah i think we really need to start now so let's begin with mj/02 as our first paper inshaAllahcan we do it already? i dont mind either way, we will waste 2 weeks if we don't start

The sequence of bases on a messenger RNA molecule is shown.
A U C G A A G U U C G U
It was transcribed from one strand of DNA.
What is the sequence of bases on the complementary,non-transcribed strand?
A.A C G A A C T T C G A T
B.A T C G A A G T T C G T
C.T A G C T T C A A G C A
D.U G C U U G A A G C U A
Y is the answer B??
Shouldn't it be C?
This question is not from the past papers..I was practicing MCQ's from another book..the question was asked therePost the link to the question and marking scheme.

1000 Biology MCQ's...the answer in the book is B btw!Mind sharing the book's name?
btw it's definitely C.

I figured out C as well!!
Aoa wr wb! I personally would prefer solving 2011 backwards..starting with nov 2011Feel free to discuss your bio p1 doubts here......and we go through each paper from 2002 towards 2011 and discuss the "hard" MCQs of each paper (or all if time isn't an issue)? This would be much better and organized rather than, say, having 5 different people posting different MCQs every minute making it hard to answer every one (idea by leosco1995 in the physics mcq thread)
Further suggestions are welcome![]()
yayyNah the book always has misprints. Congrats you were right!![]()
not a bad idea, thoughLets set a goal. Every night, everyone should post how many papers they have solved just for fun.![]()
Bro How many pp have you solved till yet?not a bad idea, though![]()
2003 and 2004 only..started todayBro How many pp have you solved till yet?
The answer in B!!! C would have been the answer had the question asked about the transcribed strand. Since, you have to figure out the sequence of bases on the non-transcribed strand, simply replace all the U's in the mRNA sequence given with T's and you'll get your answer which is B. This shortcut can also be used when they give you DNA sequence or tRNA codons and ask you to find the sequence of bases on tRNA codons or DNA. You simply replace the the Uracils with the Thymines or vice-versa. This is because you first have to find out the complementary sequence on mRNA and then again find the complementary sequence for the mRNA sequence which you just found, which brings you back to the original sequence that was given in the question.The sequence of bases on a messenger RNA molecule is shown.

Thank you..i got itThe answer in B!!! C would have been the answer had the question asked about the transcribed strand.

For this particular question 1st find the complementary sequence of bases on the DNA, which is the transcribed strand (given in option C) then again find the complementary sequence of bases on the opposite DNA strand (the non-transcribed strand, which has been asked for in the question). This brings you back to the original mRNA sequence (given in the question), with only the U's replaced with T's because its DNA and not RNA.
Can you upload this book if possible please?1000 Biology MCQ's...the answer in the book is B btw!
I figured out C as well!!
LOL seriously? He can't!Can you upload this book if possible please?
i have the same book, tell me the page no.1000 Biology MCQ's...the answer in the book is B btw!
