Chapter 14: Q. 7 (page 367)

DNA double helix does not have which of the following? a. antiparallel configuration b. complementary base pairing c. major and minor grooves d. uracil

Short Answer

Expert verified

Option d is correct.

Step by step solution

01

Step 1. Introduction

The double helical structure of DNA was given by two groups of scientists James Watson and Francis at Cambridge and Maurice Wilkins and Rosalind Franklin in London.

02

Step 2. Explanation of the correct option.

Option d is correct because uracil is not found in DNA instead thymine is found. Uracil is found in RNA.

03

Step 3. Explanation of the incorrect options.

Option a is incorrect because of the statement is correct that two polynucleotide chains have anti-parallel polarity.

Option b is incorrect because there is complementary base pairing means adenine is a complement to thymine and guanine is a complement to cytosine.

Option c is incorrect because in DNA structure two grooves are found minor and major.
