Chesapeake bay is best known for its seafood production especially blue crab ,clambs, oysters and rockfish
The rods originally contain the fuel for nuclear reactions, which mean they are highly radioactive. The radiation they emit is very dangerous and harmful to all types of life; therefore, they must be handled with care and disposed of properly to minimize damage because of them.
Answer: The West coast region has the fewest thunderstorms per year
Explanation: Oregon, Washington, California, Alaska and Hawaii are all examples of states in the west coast region of the United States.
The west coast region having the fewest thunderstorms is due to two main factors which are; coldness of the pacific ocean and the dryness of air in the region (Low humidity). These two conditions doesn't give room for the formation of any thunderstorm activity.
Bases release OH- ions in solutions, whereas Acids release H+ ions in solutions
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.
