what are the components of the dna molecule?

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).

DNA is composed of four amino acids: adenine, guanine, thymine and cytosine. Each nucleotide, or monomer, has different attributes that allow it to link with the corresponding nucleotide and form a long chain, or sequence.

DNA is made up of Nucleic acids. They are Adenine, Guanine, Thymine and Cytosine. These Nucleic acids contain sugar moiety which is made up of carbon. Thus, DNA can be considered as an organic compound.

What are the three parts of a DNA nucleotide, and how are they connected to each other? The three parts are a deoxyribose sugar, a phos- phate group, and a nitrogenous base. The phosphate group and the base are connected to different parts of the sugar.

​Nucleotide RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base.

It is a chemical made up of two long molecules, arranged in a spiral. We refer to this as the double-helix structure. DNA carries genetic information. It has all the instructions that a living organism needs to grow, reproduce and function.

They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil. The diagram below shows the structure of a DNA nucleotide. The sugar is deoxyribose, and adenine is one of four possible nitrogenous bases.

Hydrogen bonding in DNA DNA contains four bases: Guanine, Cytosine, Adenine, and Thymine. ... These hydrogen bonds between complementary nucleotides are what keeps the two strands of a DNA helix together. Each base can also form hydrogen bonds with the external environment such as with water.
