What does DNA mean? The particular order of the bases arranged along the sugar-phosphate backbone is called the DNA sequence; the sequence specifies the exact genetic instructions required to create a particular organism with its own unique traits. Each strand of the DNA molecule is held together at its base by a weak bond.

DNA A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next.DNA is often said to have a sugar and phosphate backbone..Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in base pairs, or bpthat is, the number of rungs in the ladder.he sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next.

Part 1. Chapters 1-5 of Campbell 6 thEd. Deoxyribonucleic acid (DNA) stores information for the synthesis of specific proteins. DNA has deoxyribose as its sugar. DNA consists of a phosphate group, a sugar, and a nitrogenous base. The structure of DNA is a helical, double-stranded macromolecule with bases projecting into the interior of the molecule.These two strands are always complementary in sequence.NA has a double helix structure. The outer edges are formed by alternating deoxyribose sugar molecules and phosphate groups, which make up the sugar-phosphate backbone. The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction.

- The terms phosphorus and phosphate are often used interchangeably when talking about testing, but it is the amount of inorganic phosphate in the blood that is measured with a serum phosphorus/phosphate test. Phosphates are vital for energy production, muscle and nerve function, and bone growth. They also play an important role as a buffer, helping to maintain the body's acid-base balance. Phosphorus comes into the body through the diet. It is found in many foods and is readily absorbed by the intestines. About 70-80% of the body's phosphates combine with calcium to help form bones and teeth, another 10% are found in muscle, and about 1% is in nerve tissue.

phosphate [fos′fāt]. 1 an anion of phosphoric acid. 2 a salt of phosphoric acid. Phosphates are extremely important in living cells, particularly in the storage and use of energy and the transmission of genetic information within a cell and from one cell to another.See also adenosine diphosphate, adenosine triphosphate, phosphorus.hey are continually excreted in the urine and feces, and must be replaced in the diet. Inorganic phosphates function as buffer salts to maintain the acid-base balance in blood, saliva, urine and other body fluids. The principal phosphates in this buffer system are monosodium and disodium phosphate.

What is DNA? (A grouping like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.he specific base pairing provides a way for DNA to make exact copies of itself. Each half of the original DNA still has a base attached to its sugar-phosphate backbone. A new strand of DNA is made by an enzyme called DNA polymerase. It reads the original strand and matches complementary bases to the original strand.
