The answer would be D. All of the above because A, B and C are also true.
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.
GMOs have been changing the way that pesticides are used in agriculture. Herbicide-tolerant genetically modified (GM) crops have led to an increase in herbicide usage while insecticide-producing GM crops have led to a decrease in insecticides.
Answer: Two characteristics define brightness: luminosity and magnitude. ... The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth. brainliest?
