“A type of nucleic acid, the genetic material of us, made up of sugar, phosphate and nitrogenous bases and a polynucleotide chain known as DNA- deoxyribose nucleic acid which store and transfer biological information.” Structure of DNA:
Read it here: Extrachromosomal or organelle DNA. We had written an amazing article on present topics. Those type of DNA is known as extrachromosomal or cytoplasmic DNA. The DNA is present in a cell nucleus, known as the genome of an organism, but some DNA is also present in membrane-bounded organelles such as mitochondria and chloroplast. The acidic nature of it, is because of the phosphoric acid present on the backbone which is neutralized at pH 7.8 to 8.8. The nucleic acid is a long chain of nucleotides known as a polynucleotide chain– a class of biopolymers. Besides storing the information, both transfer the information too. DNA is present in almost every organism except some viruses having RNA as their genetic material. Both chemicals are information storage units, we can say. The DNA is a deoxyribonucleic acid while the RNA is ribonucleic acid. The nucleic acid was first isolated by Friedrich Miescher in 1869 and named it as “nuclei”, although the name nucleic acid was given by Richard Altmann in 1889. Different types of DNA based on their location:Ī nucleic acid is an alkaline chemical present in a cell nucleus in the form of either ribonucleic acid or deoxyribonucleic acid.Different types of DNA based on their topology.With that, we will also cover some other information on DNA. Furthermore, We will give you some evidence that proves DNA as genetic material. In the present articles we will talk only about DNA its structure, function and location. These all are various types of proteins and encoded from DNA via mRNA intermediate, henceforth, we can say DNA is a basic unit for every living entity. Thus information in DNA is crucial for us. Various biological reactions and functions performed by different molecules like enzymes, receptors, chaperons, immunoglobulins are peptides that are actually manufactured from DNA. The information encoded in the DNA decides the function and structure of various biomolecules. Therefore it is very essential for our survival. It stores and transfers biological information from one organism to another. As it transfers or inherited information alterations and traits are also inherited into consecutive generations. The life expectancy of every living entity on earth depends on the DNA, hence, it is as important as water and oxygen. “Deoxyribonucleic acid, DNA is the genetic material of us, made up of the deoxy sugar, phosphate and nitrogenous bases.”
