DNA and RNA
Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, deoxyribonucleic acid, is one of the natural components. Deoxyribonucleic acid is a double-stranded molecule. Watson and Crick postulated the double-stranded model of the helix. A deoxyribonucleic acid is a molecular group that carries and transmits genetic information from parents to offspring. All eukaryotic and prokaryotic cells are involved.
DNA as the Genetic Material
DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it as a genetic component. Certain organisms have different types of nucleic acids as their genetic material - DNA or RNA.
Genetics
The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents several diseases in a human being. Thus, genetics also creates an understanding of various medical conditions.
DNA Replication
The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.
What forms the basis of tetranucleotide hypothesis for DNA structure ?
American biochemist Phoebus Aaron Theodore Levene investigated the structure and function of nucleic acids. He distinguished between DNA and RNA, the two types of nucleic acid. He also discovered adenine, guanine, thymine, cytosine, deoxyribose, and a phosphate group in DNA. Before Erwin Chargaff's later work, it was commonly assumed that DNA was arranged into repeating tetranucleotides in such a way that genetic information could not be carried. Instead, it was thought that the protein component of chromosomes was the source of heredity; prior to the 1940s, most studies on the physical origin of the gene concentrated on proteins, particularly enzymes and viruses.
