What is the correct sequence of the complementary strand for the given portion of a DNA molecule:- $5' - G A C G T A C - 3'$?

$RNA$ is different from $DNA$ because $RNA$ contains

In the $DNA$ of $E. coli$,the mole ratio of adenine to cytosine is $0.7$. If the number of moles of adenine in the $DNA$ is $350000$,the number of moles of guanine is equal to:

The average energy of each hydrogen bond in $A-T$ pair is $x \, kcal \, mol^{-1}$ and that in $G-C$ pair is $y \, kcal \, mol^{-1}$. Assuming that no other interaction exists between the nucleotides,the approximate energy required in $kcal \, mol^{-1}$ to split the following double stranded $DNA$ into two single strands is:
$A$-$T$-$A$-$T$-$G$-$C$-$A$-$G$
| | | | | | | |
$T$-$A$-$T$-$A$-$C$-$G$-$T$-$C$

Which of the following is not present in nucleic acids?

Chargaff's rule states that in an organism
