Read the below Statements about the structure of genetic material and identify the correct ones. I. Adenine and guanine are bases that have a double ring structure , cytosine, thymine and uracil are based with a single ring structure . II. An adenine nucleotide from DNA is the same as an adenine nucleotide from RNA , DNA adenine pairs with uracil and RNA adenine pairs with thymine. III. The base pairing that occurs in a double DNA helix and when RNA is synthesised during transcription follows the rule that a purine pairs with a pyrimidine. IV. The two Polynucleotides on a DNA molecule run in opposite directions so that the double helix formed has two strands that are parallel to each other.

You are given two compound First, you name both of them the same yet, are they really same structure, or they some how different ?Carefully inspection should convince you that they are indeed different. Now, how their physical and chemical properties differ? Generally (i) cis-isomer has more diplomoment than trans-isomer (ii) cis-is less stable than trans (iii) boiling points of cis isomers are than those of trans isomers (remember boiling points are directly related to polarity which is determined by dipolemoment) chemical reactivities of cis and trans also differ from each other. Which of the following statements best explain(s) the relationship between two isomer of CH_(3)-CH=CH -CH_(3) ?
