DNA Sequences, Unique

AGNIESZKA LICHANSKA

Deoxyribonucleic acid (DNA) contains genetic information of an organism that is unique for each organism. The entire cellular DNA of any organism, bacteria, plant or animal is known as its genome, as is the entire genetic material of a virus. A DNA sequence is considered to be unique if it is present in only one copy in a haploid genome. A haploid genome contains only a single copy of each chromosome. In humans, for example, a haploid number of chromosomes is 23. However, not all of the DNA contained in the genome is considered as unique; there are also various repetitive sequences present.
