the answer is A because A always goes with T
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.

The Endoplasmic reticulum is a series of pipes and it moves in the cell. Without the E.R., the protein factory (ribosomes) would not be able to ship the proteins and cells would starve to death. Hope this helped!
Answer:
It is important to have a standardized system of classification so people can easily identify different things. It allows scientists to identify, name and group different organisms. It is important so scientists are able to easily communicate about different organisms without confusion.
It is necessary to classify organisms because: It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences
if Linnaeus had not developed the taxonomy system there would be no organized way of naming or categorizing new organisms in the scientific community and around the world. Instead, all organisms would be categorized differently in every part of the world, with different names.if Linnaeus had not developed the taxonomy system there would be no organized way of naming or categorizing new organisms in the scientific community and around the world.
