Introduction RNA is the ribonucleic acid molecule that is composed of polynucleotide chains arranged in a single strand and are folded onto themselves instead of pairing as a double helical strand. RNA is responsible for playing a major role in various functions of the body including the coding, decoding, expression and regulation of genes. RNA […]

Introduction DNA is the Deoxyribonucleic acid molecule that is composed of various groups and two polynucleotide chains that are arranged in an antiparallel manner and are coiled around each other to form a double helix structure of DNA. DNA is responsible for carrying the genetic information from the parents to the next generation in almost

Nucleic acids are long-chain polymeric molecules that are majorly of two different types. Deoxyribonucleic acid, known as DNA, and ribonucleic acid, is known as RNA. DNA and RNA are the genetic material present in all humans, living organisms, and viruses that are nucleic acids. In this study material notes on Nucleic Acids & Their Chemical

Introduction Nucleic acids come under the category of macromolecules that are made up of repeating units of polymers. The two most important and known macromolecules are DNA and RNA. The nucleic acid helps in the storage of genetic information and then transfers it to the next generation. DNA helps in encoding the information that the

A meristem is a simple tissue composed of a group of similar and immature cells that repeatedly undergo mitotic divisions to form new cells. Meristematic tissue is a mass of undifferentiated cells that undergo repeated cell division. Have isodiametric, rounded, oval or polygonal shaped immature cells with no intercellular spaces. Have thin, elastic walls, made

Nucleic acids can be defined as the organic materials present in all organisms on this planet in the form of RNA and DNA. These acids are a combination of sugar molecules, phosphate groups, and nitrogenous bases linked together through several different bonds in a series of sequences. The DNA structure speaks about the basic genetic

Nucleic acids are specific large molecules in the cells present in all organisms. DNA and RNA are the two primary nucleic acids. These acids are a combination of sugar molecules, phosphate groups, and nitrogenous bases. DNA’s double helix structure resembles a twisted ladder, whereas the structure of RNA resembles a hairpin. Although RNA and DNA

DNA or deoxyribonucleic acid is a long patch that contains our unique inheritable decalogue. It holds all the instructions for the formation of all the proteins in our bodies. The function of DNA is to store all of the inheritable information that an organism needs to develop, function, and reproduce. It’s the natural instruction manual

The improvement of anti-toxins has enormously added to the long and solid lives people appreciate today. It has additionally expanded the hope of life. The increase in the population has caused many issues regarding food assets, business, natural problems, etc. To keep away from these issues, populace development should be controlled. These issues have prompted
