Assertion : Amino acids are called alpha -amino acids. Reason : Amino acids are organic compounds containing an amino group and an acidic group as substituents on the alpha -carbon.

Assertion : The heterocyclic compounds in nucleic acid are the nitrogenous bases. Reason : Adenine and guanine are substituted pyrimidines while uracil, cytosine and thymine are substituted purines.

Assertion: Purine bases present in DNA are adenine and guanine. Reason: The base thymine is present in RNA while base uracil is present in DNA.

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 anti-parallel to each other.
