Reactions that hydrolyze the phosphodiester bonds split the DNA molecule between the phosphate groups and the hydroxyl groups of the two sugar groups.
In DNA there is a covalent bond through a phosphate group that connects the hydroxyl group (OH) at the 5' position of the pentose sugar and the hydroxyl group at the 3' position of the pentose sugar of the next nucleotide. This covalent bond is called a phosphodiester bond because chemically the phosphate group is in the diester form.
In other words, the phosphodiester bond connects the sugar in one nucleotide to the sugar in the next nucleotide, so this bond simultaneously connects the two consecutive nucleotides to form a polynucleotide chain. If there is an enzyme that catalyzes the hydrolysis of covalent bonds that combine nucleotides, what happens is that the phosphodiester link between deoxyribose sugars will break.

Answer:
the animals
Explanation:
the difference between animal life in the Mesozoic Era and the early Cenozoic Era is that in the Mesozoic Era the reptiles were dominate and in the Cenozoic Era the mammals were dominate.
The food chain is a system in which food is connected with the ecosystem. Ex:composers, producers, decomposers,etc.
Epididymis would be the correct answer, can i get brainliest please
Platelets start a clotting reaction that intimately produces a clot composed of fibrin, is a form of Fibrinogen
Explanation:
Fibrinogen is blood plasma Protein which is converted into those protein fibrins in the clotting process. After removal of clot the fibrinogen free fluid is obtained and this fluid is known as blood serum. It shows strong flow birefringence. It is highly viscous.
By half saturation process and using the sodium chloride fibrinogen can be participated from the blood plasma. Through thrombin process clotting is initiated. With the help of electron micrographs, its molecules look like a rod whose length is 47.5 nanometre.
