5.Molecular Basis of Inheritance
normal
During transcription, if the nucleotide sequence of the $DNA$ strand that is being coded is $ATACG$; then the nucleotide sequence in the $mRNA$ would be
A
$UAUGC$
B
$UATGC$
C
$TATGC$
D
$TCTGG$
(AIPMT-2004)
Solution
(a)Bases sequence in $DNA$ will decide the base sequence in $RNA$. Uracil $(U)$ will work as substitute for thymine $(T)$ in $mRNA$. Complementary base pairing for $mRNA$ will be $\begin{array}{*{20}{c}}{\rm{A}}&{\rm{T}}&{\rm{A}}&{\rm{C}}&{\rm{G}}\\{\rm{U}}&{\rm{A}}&{\rm{U}}&{\rm{G}}&{\rm{C}}\end{array}$.
