Introns are crucial because the protein repertoire or variety is greatly enhanced by alternative splicing in which introns take partly important roles. Alternative splicing is a controlled molecular mechanism producing multiple variant proteins from a single gene in a eukaryotic cell. The average identity levels in the immediately flanking intronic sequences were 88% and 80% for the upstream and downstream introns, respectively, higher than the conservation levels of 77% that were measured in promoter regions. Our results suggest that the function of many of the intronic sequence blocks that are conserved between human and ...

When they leave the chromosome, they can also take flanking sequences with them, creating deletion mutations, or insertion mutations if they are inserted into a gene. There are two major classes of transposons, which make up about 10% of the genome: • Short interspersed nuclear elements (SINES) are 100 to 500 base pairs in length.
