The total number of hydrogen bonds of a DNA-double Helix strand whose one strand has the following sequence of bases is_______. 5^ - G - G-C-A-A-A-T-C-G-G-C-T-A-3'

Step-by-step solution

Two nucleic acid chains are wound about each other and held together by H bonds between pair of bases. Adenine from two hydrogen bonds with thymine and Guanine form three hydrogen bond with cytosine. 5^ G - G - C - A - A - A - T - C - G - G - C - T - A -3^ In given DNA strand total seven guanine and cytosine bases which form total 21 H -bonds and six adenine and thymine base which will form total 12 H-bonds with other DNA strand. Total no. of H bonds =7 3+6 2=33
