Summary Introduction

Nucleotides are building blocks of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). The nucleotide is composed of a nitrogenous base, sugar, and phosphate group. DNA is a genetic material, which consists of a long stretch of nucleotide sequences. DNA carries genetic information from mother to offspring in both prokaryotes and eukaryotes. Replication, transcription, and translation are important processes of the central dogma of biology. A change in the DNA sequence of the cell is known as a mutation. Mutations can affect the phenotype of an organism.
