A bioinformatics database compresses clinical genetic sequences (composed of sequences of A, C, G, and T representing nucleotides) for long-term storage. If even a single character is modified or omitted during compression, the clinical analysis software will output an incorrect diagnostic report.
State the class of compression that must be used to compress these files.
Practise Edexcel GCSE Computer Science Data storage and compression with exam-style questions for GCSE Computer Science. 50 questions covering Binary multiples and file size calculations and Need for and methods of compression, matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
