what are the three parts of a dna monomer

The DNA mote consists of three parts *nitrogenous base *deoxyribose sugar and *phosphate group.
The nitrogenous bases are nothing but cyclic carbon molecules that may or may non contain nitrogen groups attached to IT. They are divided into ii types :purines and pyrimidines.the purine consists of the adenine and guanine bases whereas the pyrimidines consists of the thymine and C.the nitrogenous bases are attached to sugar atom.the simoleons molecule is pentose in structure.it is called the deoxyribose as it is goose egg just the ribose sugar that lacks the oxygen atom in its 2' position.the 5' atomic number 6 is attached to the phosphate group .the phosphate is a pentavalent tripinnate with a double bonded oxygen and 3 single attachment hydroxyl molecules

The structure of Desoxyribonucleic acid was first described in 1953 by James Watson and Francis Crick. That is why a common stunt man helical representation of the DNA is referred to A the Watson and Crick role model. The DNA molecule is a twofold stranded helix that curls more or less a middle axis. The 2 helices are joined away atomic number 1 bonds.
The monomers that make ascending a DNA molecule are called nucleotides. Each nucleotide contains one nitrogenous base (purines operating theater pyrimidines). The purines let in A and guanine and pyrimidines include C and thymine (replaced by uracil in RNA). Besides the bases, apiece nucleotide has a phosphate group attached to it besides as a sugar radical (ribose). Joined conjointly, these reach peerless nucleotide.
Complementary nucleotides align next to apiece other (Adenine with T and guanine with cytosine). Once they sustain positioned themselves, hydrogen bonds are formed between them that 'zip' the cardinal strands together. Adenine and thymine have 2 hydrogen bonds between them and G and cytosine have 3. The backbone of DNA is made from the sugar phosphate groups and nucleotides determine the sequence of genetic code.
Well-nig 10 nucleotide pairs match into unmatchable helical turn and one helical work is nearly 3.4nm.

The DNA molecule is made up of 2 long polymers connected by the bonding of atomic number 1 atoms and coiled in the shape of double Helix. Each of the cardinal polymers contains many structures which are called nucleotides, which, in turn, are foster distributed down into three parts: Deoxyribose, a phosphate group, and a gas base.

The three main parts that are in the DNA molecule are nitrogen for base, lucre and phosphate

DNA stands for DNA. It is basically a nucleic acid which contains genetic book of instructions that are ill-used in growth and functioning of every living being and even some viruses. Desoxyribonucleic acid is causative storing selective information for long term.

The structure of DNA was first described by James Watson and Francis Crick in the class 1953. It is characterized by a right handed double helix that has 10 nucleotide pairs per helical turn. For each one of the whorl strands is composed of sugar phosphate and attached bases. Each of these strands are connected to a complementary strand through atomic number 1 bonding between each of the paired bases. The structure is such that adenine pairs up with Thymine and G pairs functioning with cytosine.

Desoxyribonucleic acid contains the following:

Ribose, a sugar

A phosphate grouping (a phosphoric atom surrounded by oxygen atoms)

Nitrogenous bases: A, guanine, T, and cytosine (ofttimes abbreviated every bit A, G, T, C)

Ribose molecules and phosphate groups combine to mould the sugar-phosphate backbone, which are the two long "strands" of DNA that keep down the nitrogenous bases

Henry James Watson and Francis Crick continued Rosalind Franklin's study of DNA. The two of them concluded that DNA has a spiral shape and as a result won the Alfred Nobel Prize.

DNA contains about 2 genes which coil round each other.

DNA contains the following:

• Ribose, a refined sugar


• A phosphate group (a phosphoric atom surrounded by oxygen atoms)


• Nitrogenous bases: A, guanine, thymine, and cytosine (ofttimes abbreviated American Samoa A, G, T, C)

Ribose molecules and phosphate groups combine to form the sugar-orthophosphate backbone, which are the two long "strands" of Desoxyribonucleic acid that hold the nitrogenous bases.
