How is dna compressed into chromosomes

WebGeneral text compression algorithms don’t utilize the specific characteristics of a DNA sequence. DNA specific compression algorithms exploit the repetitiveness of bases in DNA sequences. A repetitive DNA sequence can be best compressed using dictionary based compression algorithm. Non-repetitive parts of WebFor males it would be 23 + 1 chromosome in data storage on a HDD and for females 23 chromosomes, explaining the little differences mentioned now and then in answers. The X chrom. from males is equal to X chrom. from the females. Thus loading the genome (23 + 1) into memory is done in parts via BLAST using constructed databases from fasta-files.
