Compression Techniques for DNA Sequences: A Thematic Review
Rosario Gilmary,Akila Venkatesan,Govindasamy Vaiyapuri 한국정보과학회 2021 Journal of Computing Science and Engineering Vol.15 No.2
Deoxyribonucleic acid (DNA) is the basic entity that carries genetic instructions. This information is used in the evolution, progression, and improvement of all species. It is estimated that 10 CD-ROMs are required to store the genomic data of an individual being. With the increase in DNA sequencing equipment, an extensive heap of genomic data is created. The increase in DNA data in public databases is surpassing the rate of growth in storage space, thereby raising a significant concern related to data storage, transmission, retrieval, and search. To reduce the data storage and storage expense, lossless compression procedures were applied. Conventional compression methods are not proficient while compressing the biological data. Hence, several unique and contemporary lossless compression mechanisms were used to achieve improved compression ratio in biological sequences. Here, we scrutinize the diverse existing compression procedures that are appropriate for the compression of DNA sequences. The efficiency of algorithms is compared in terms of compression ratio, the ratio of the capacity of the compressed folder, and compression/decompression time. Main challenges and future research directions in DNA compression are also presented. Emphasis has been given to special references related to contemporary techniques.
