DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen to DNA molecules treated with DNAase?
A) The purines would be separated from the deoxyribose sugars.
B) The pyrimidines would be separated from the deoxyribose sugars.
C) All bases would be separated from the deoxyribose sugars.
D) The two strands of the double helix would separate.
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Answer:
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Explanation:
The purines and pyrimidines of two DNA strands of a DNA duplex are held together by hydrogen bonds. Hydrogen bonds are not covalent bonds. The enzyme DNAase targets the phosphodiester bonds. These are the covalent bonds that join two deoxyribonucleotides of a DNA strand together. therefore, when a DNA is subjected to digestion with DNAase enzyme, the phosphodiester bonds will be broken that hold the pentose sugars of two nucleotides by a phosphate group.
Answer: D
Explanation: i've taken bio
Hey, I believe your answer would be D. Only DNA contains the sugar deoxyribose. This is the answer, because RNA contains sugar ribose, not sugar deoxyribose.
Answer:
<em>Applications of dipole moment:
</em>
<em>
</em>
<em>(i) Ionic character can be calculated using the value of dipole moment.
</em>
<em>
</em>
<em>% of ionic character =
</em>
<em>
</em>
<em>=100* (Experimental value of dipole moment/Theoretical value of 100% ionized molecule)
</em>
<em>
</em>
<em>(ii) Geometry of the molecule can be predicted using the dipole moment.
</em>
<em>
</em>
<em>(iii) Dipole moment is helpful in predicting nature of the molecule. Weather it is polar or non-polar in nature.

<span>Photosynthesis. Photosynthesis is a process whereby green plants and other organism like bacteria produce their food using organs like chlorophyll in plants and plasma membrane in bacteria to convert solar energy into chemical energy. The energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. Most plants, algae, and cyanobacteria perform photosynthesis. These organisms and plants produce organic waste product like water and Oxygen which is essentially for life on earth.</span>
