Answer:
Introduction: The ECOR1 enzyme is a restriction enzyme that cleaves DNA at specific sites and produces sticky ends. The palindromic sequences of DNA are recognized by ECOR1, and the enzyme breaks the phospho ester bonds and hydrogen bonds in the DNA molecule.
The ratio between phospho ester bonds and hydrogen bonds:
- Phospho ester bonds are covalent bonds that hold together the sugar-phosphate backbone of DNA.
- Hydrogen bonds are non-covalent bonds that hold together the complementary base pairs in DNA.
- The ratio between phospho ester bonds and hydrogen bonds that are broken in each palindromic sequence of a DNA, when treated with ECOR1 is 1:2.
Explanation:
- ECOR1 recognizes the specific palindromic sequences in DNA and cleaves the phospho ester bonds between the sugar and phosphate groups at these sites.
- The cleavage of the phospho ester bonds produces sticky ends that can anneal with complementary sticky ends produced by cleavage at another ECOR1 site.
- When the sticky ends anneal, the hydrogen bonds between the complementary base pairs are formed.
- Therefore, for each phospho ester bond that is cleaved by ECOR1, two hydrogen bonds are formed.
- This results in a ratio of 1:2 between the phospho ester bonds and hydrogen bonds that are broken in each palindromic sequence of DNA treated with ECOR1.
Therefore, the correct answer is option 2) 1:2.
