Answer:
DNA is more stable than RNA due to the absence of a hydroxyl group in the 2' position of the deoxyribose sugar.
Explanation:
- Each RNA or ribonucleic acid molecule is composed of a pentose sugar called Ribose, a phosphate group and a nitrogenous base.
- A RNA chain is made up of a ribose phosphate backbone linked by phosphodiester bonds.
- The Ribose sugar has a hydroxyl group in the 2' position.
- This hydroxyl group is susceptible to hydrolysis in presence of alkaline condition.
- This hydrolysis causes the breakdown of the phosphodiester linkage between the phosphate group and the ribose sugar, causing the disruption of the entire RNA structure.
- Each DNA or deoxyribonucleic acid is composed of a pentose sugar called Deoxyribose, a phosphate group and a nitrogenous base.
- A DNA chain is made up of a deoxyribose phosphate backbone linked by phosphodiester bonds.
- In the Deoxyribose sugar, the 2' hydroxyl group is absent and hence it is no longer susceptible to hydrolysis under alkaline conditions.
- Hence, DNA is more stable than RNA.
Explanation:
Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.
Domain bacteria, Domain Archaea and Domain Eucarya
Answer:
Emile Durkheim argued that society was like a human body (the organic analogy). Society was made up of various institutions that acted like the organs of the body: they all needed to be functioning properly for the body to function.
Explanation:
Those would be oceans and lakes. Hope this helps and have a nice day!
