A DNA segment has the following sequence 5'-CCGAAT-3'. What would be the sequence of the transcribed m-RNA?
Answer:5'-AUUCGG-3'
WHY?
I thought the answer was 5'-GGCUUA-3'?
Can anyone tell me where did mine reasoning went wrong?

 

[Svart Aske]

The mRNA is transcribed antiparallel to the template DNA.

Because it will be transcribed with 3'5' opposite the 5'3'. Therefore the one that has the correct 3'5' arrangement is 5'-AUUCGG-3'

5'-AUUCGG-3' is the same thing as: 3'-GGCUUA-5'.

3' --> 5' DNA coding strand / sense strand
5' --> 3' DNA non-coding strand / anti-sense
3' --> 5' mRNA
5' --> 3' tRNA binds to mRNA producing the protein (which is coded from the 3' --> 5' mRNA and 3' --> 5' DNA.)

See how important the order is?

If the protein is translated from the non-coding strand (eg the mRNA is transcripted from the DNA non-coding strand) then the protein will be something completely different.
