Question

In one polynucleotide strand of a $DNA$ molecule the ratio of $A+T/G+C$ is $0.3$. What is the $A+G/T+C$ ratio of the entire $DNA$ molecule?

Answer 1

• A+T/G+C is ratio which is different for different for different species, but constant for particular species.
  
• A+T/G+C is constant for all double-stranded DNA and its value is 1 because for dsDNA A=T are always same in number similarly G&C is also the same number.
