Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA ? a) 5´-AGCT-3 ´ with 5´-TCGA-3 ´ b ) All of these pairs are correct . c ) 5´-ATGC-3 ´ with 5´-GCAT-3 ´ d ) 5´-GCGC-3 ´ with 5´-TATA-3 e ) 5´-purine-pyrimidine-purine-pyrimidine-3 ´ with 3´-purine-pyrimidine-purine-pyrimidine -5´ ... Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA ? 5´-AGCT-3 ´ with 5´-TCGA-3 ´ 5´-ATGC-3 ´ with 5´-GCAT-3 ´ 5´-purine-pyrimidine-purine-pyrimidine-3 ´ with 3´-purine-pyrimidine-purine-pyrimidine -5´ All of these pairs are correct . 5´-GCGC-3 ´ with 5´-TATA-3 A) The two strands of the double helix would separate. B ) The phosphodiester linkages of the polynucleotide backbone would be broken. C ) The purines would be separated from the deoxyribose sugars. D ) The pyrimidines would be separated from the deoxyribose sugars. E ) All bases would be separated from the deoxyribose sugars. Answer: D ) 5' -ATGC-3 with 5' -GCAT-3 Explanation: In a double helix DNA adenine always pairs with thymine and cytosine pairs with guanine. Also the two strands of a double helix DNA are antiparallel that is the 5' end of one strand lies opposite to the 3' e...
