A medical diagnostic system at a remote field clinic needs to transmit patient DNA sequence records, stored as plain text files containing long sequences of genetic bases, to a central reference laboratory. Due to limited satellite bandwidth, the data files must be compressed before transmission.
Identify the most suitable type of compression for the DNA sequence records and justify your choice.
