AbstractAbstract

►This project examines the randomization This project examines the randomization of DNA sequences based on current of DNA sequences based on current genome sequencing projects. Using genome sequencing projects. Using computational programs, mainly R and computational programs, mainly R and MATLAB, different mathematical tests for MATLAB, different mathematical tests for randomness are applied to DNA randomness are applied to DNA sequences in an attempt to find patterns sequences in an attempt to find patterns or other unique properties. DNA or other unique properties. DNA sequences used are obtained from the sequences used are obtained from the Virtual Library of Genetics.Virtual Library of Genetics.
