DNA is a genetic material, consisting of long stretch of nucleotide sequence with 2 m length. It carries genetic information from one generation to another. A complete set of genetic materials (both coding and non-coding regions of DNA) of an organism is called the genome. The total human genome consists of about 3.1 billion base pairs and nearly 20,000 protein coding genes. DNA replication is the first step in the central dogma of biology followed by transcription and translation. In replication, two identical copies of DNA sequences are produced from the single DNA sequence. Synthesis of mRNA from DNA is known as transcription, followed by translation, in which protein is synthesized from the mRNA sequence.
