title,doi,url,abstract,journal,publication_year,pmid,arxiv A Relative Study on Existing Two Bit-Based DNA Compression Techniques with Bit DNA Squeezer (BDNAS), https://doi.org/10.32628/IJSRCSEIT, https://ijsrcseit.com/CSEIT1725226, Compression can ease the burden of storage transfer retrieval and searching of data. DNA databases are growing intensively leading to the demand for more sophisticated compression tools. Compressing DNA data is different from compressing any other text since DNA sequences are essentially made us of combinations of four nucleotides Adenine (A) Thymine (T) Cytosine (C) or Guanine (G) which queue up in a particular sequence and make a long string of repetitive and non- repetitive sequences. Recently the explosion in Bio Informatics has drawn attention towards DNA storage and banking. DNA banks are growing rapidly as newer samples of DNA sequences are being accumulated. This paper deals with comparative study of existing two bit based DNA compression techniques such as GENBIT DNABIT HUFFBIT GENCODEX with one bit based BDNAS (Bit DNA Squeezer) algorithm. , International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2017, CSEIT1725226
