The total number of hydrogen bonds of a DNA-double Helix strand...
The total number of hydrogen bonds of a DNA-double Helix strand whose one strand has the following sequence of bases is_______.
- G - G-C-A-A-A-T-C-G-G-C-T-A-3'
- G - G-C-A-A-A-T-C-G-G-C-T-A-3'
Correct answer
0
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.
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
Adenine from two hydrogen bonds with thymine and Guanine form three hydrogen bond with cytosine.
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
