A non-template strand of DNA contains the sequence TAC-GAG- TAG- CCT.?

What sequence of tRNA nucleotides would correspond to this sequence?


a. uac-gag-uag-ccu


b. aug-cuc-auc-gga


c. uac-gag-agg-ccu


d. atg-ctc-atc-gga

A non-template strand of DNA contains the sequence TAC-GAG- TAG- CCT.?
First thing you must know:


If it is replication (DNA to DNA), A pairs up with T and G pairs up with C.





if it is transcription (DNA to RNA), A pairs with U, T pairs with A, and G pairs with C.





Always remember T (thymine) does not exist in RNA.





To get the tRNA sequence, you must first know the template DNA where the tRNA be transcribed.





non-template: TAC-GAG-TAG-CCT


template DNA: ATG-CTC-ATC-GGA


mRNA: UAC-GAG-UAG-CCU





mRNA is the one that is produced from the DNA template.





So to get the tRNA sequence, you must use the mRNA sequence to get the answer.





tRNA: AUG-CUC-AUC-GGA





the answer is (b)
Reply:DNA: TAC-GAG-TAG-CCT


mRNA: AUG-CUC-AUC-GGA


tRNA: UAC-GAG-UAG-CCU





So your answer would be (A).

Reply:the answer is NOT A


if the NON template strand is tac gag tag cct


then the template strand is atg ctc atc gga


so the mrna strand is uac gcg uag cct


so the trna has to correspond to that which makes it aug cgc auc gga


so the answer is B
Reply:c. uac-gag-agg-ccu
Reply:The answer is A).





Non template strand: TAC-GAG-TAG-CCT


Template strand: ATG-CTC-ATC-GGA


tRNA: UAC-GAG-UAG-CCU
