What is DNA?<\/b><\/h2>\n

DNA (Deoxyribonucleic Acid)<\/b> is the primary genetic material found in almost all living organisms. It contains the instructions required for the development, growth, reproduction, and functioning of cells.<\/span><\/p>\n

DNA is mainly located in the <\/span>cell nucleus<\/b> and forms structures known as chromosomes. The structure of DNA is a <\/span>double helix<\/b>, which looks like a twisted ladder. This structure was discovered by <\/span>James Watson<\/b> and <\/span>Francis Crick<\/b> in 1953.<\/span><\/p>\n

DNA is composed of smaller units called <\/span>nucleotides<\/b>, and each nucleotide contains three components: a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogen bases present in DNA are <\/span>Adenine (A), Thymine (T), Cytosine (C), and Guanine (G)<\/b>.<\/span><\/p>\n

What is RNA?<\/b><\/h2>\n

RNA (Ribonucleic Acid)<\/b><\/a> is another important nucleic acid that plays a key role in <\/span>protein synthesis<\/b>. Unlike DNA, RNA is usually <\/span>single-stranded<\/b> and can move from the nucleus to the cytoplasm.<\/span><\/p>\n

RNA helps convert the genetic information stored in DNA into proteins that perform various functions in the body. It acts as a messenger and functional molecule in cells.<\/span><\/p>\n

RNA is made up of nucleotides containing <\/span>ribose sugar<\/b>, a phosphate group, and nitrogenous bases. However, RNA contains <\/span>Uracil (U)<\/b> instead of Thymine.<\/span><\/p>\n

DNA Fingerprinting<\/b><\/h2>\n

DNA fingerprinting<\/b> is a scientific technique used to identify individuals based on unique patterns in their DNA. While traditional fingerprints at the tips of fingers have long been used for identification, they can sometimes be altered by injury or surgery. DNA patterns, however, remain <\/span>unique and permanent for each individual<\/b>.<\/span><\/p>\n

Uses of DNA Fingerprinting<\/b><\/p>\n

DNA fingerprinting is widely used in several important fields:<\/span><\/p>\n
