The biological description of the nucleotides

About the book Description Electrochemistry of Biological Molecules presents a fairly complete summary of the electrochemistry of the more important groups of nitrogen heterocyclic molecules including purines and pyrimidines and their nucleosides and nucleotides, polynucleotides and nucleic acids, pteridines, flavins, pyrroles, porphyrins, and pyridines. Topics covered range from the theory and instrumentation of electrochemistry to various biological molecules, including pteridines, isoalloxazines, flavins, and flavin nucleotides. Comprised of nine chapters, this book begins with an overview of electrochemical techniques and their use to study biological materials, followed by a discussion on the theory and instrumentation of electrochemistry, with emphasis on their significance and utility as well aa their principles and circuits. Subsequent chapters explore nitrogen heterocyclic molecules such as purines and pyrimidines and their nucleosides and nucleotides, polynucleotides and nucleic acids, pteridines, flavins, pyrroles, porphyrins, and pyridines.

The biological description of the nucleotides

Both have sets of nucleotides that contain genetic information. Deoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.

Each nucleotide contains a phosphate group, a sugar group and a nitrogen base.

The biological description of the nucleotides

The four types of nitrogen bases are adenine Athymine Tguanine G and cytosine C. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix.

The bases on one strand pair with the bases on another strand: Each chromosome contains a single DNA molecule. But for many years, researchers did not realize the importance of this molecule. It was not until that James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin figured out the structure of DNA — a double helix — which they realized could carry biological information.

Unraveling the Human Genome: The technology can be used to determine the order of bases in genes, chromosomes, or an entire genome. For instance, mutations in the BRCA1 and BRCA2 genes are known to increase the risk of breast and ovarian cancer, and analysis of these genes in a genetic test can reveal whether a person has these mutations.

There are now many at-home genetic testing kits, but some of them are unreliable. Movies were also encoded data to make a short video in the DNA molecules of bacteria in DNA was used as code for each pixel of the movie.Nucleic acids are macromolecules that store genetic information and enable protein production.

Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, . A nucleotide is one of the structural components, or building blocks, of DNA and RNA.

A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid. Made up of units called nucleotides, the nucleic acid DNA contains the genetic blueprint that influences your personal characteristics, while the nucleic acid RNA pulls together amino acids to form new proteins as your cells need them.

The phosphate group is bonded to the 5 carbon of the sugar (see Figure 2), and when nucleotides are joined to form RNA or DNA, the phosphate of one nucleotide is joined to the sugar of the next nucleotide at its 3 carbon, to form the sugar-phosphate backbone of the nucleic acid.
