Image
Deoxyribonucleic acid, or DNA, has long been hailed as the molecule that holds the blueprint of life. This twisted ladder-shaped molecule, discovered in 1869, stores the instructions needed to build and maintain an organism. But DNA is a dynamic molecule, and recent research continues to unveil its complexities. The Basic Building Blocks: DNA is made up of smaller units called nucleotides. Each nucleotide has three components: Sugar: Deoxyribose sugar forms the backbone of the DNA molecule. Phosphate group: This group links the nucleotides together to form a chain. Nitrogenous base: There are four types of nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases form the rungs of the DNA ladder and hold the genetic code. [Insert a diagram of DNA structure here, showing the sugar-phosphate backbone, nitrogenous bases, and hydrogen bonds] The Code of Life: The order of the nitrogenous bases in the DNA sequence is the genetic code. Think of it li...

Today we are going to talk about the membranous coverings of the central nervous system        Right there are three types of membranes which are enveloping around the brain in the spinal cord right let me show you that by a simple diagram first of all suppose here is your central ner vous system of course you'd recognize these structures right now the first covering which is very very intimately covering the central nervous system is Piatt met by a metal is the connective tissue layer which is highly vascular it is highly vascular very delicate very thin very closely covering all the surfaces of brain and spinal cord right and this paya meta this moves throughout with the central nervous system right so we can say that this black layer is pyometra what is meant by the paya matter what is meant by the word paya and mater just who'll tell me anyone yes , very good  paya means soft and mater means mother so it's a soft mother taking care of the central nerv...
