[Variations of the length of exons and introns in human genome genes]
Abstract:
The exon-intron organization of genes of all human chromosomes was studied in relation to the density of gene distribution on DNA strands and on the number of introns in genes. The lengths of exons, introns and genes have been found to vary correlatively, and this correlation depends on the density of genes in human chromosomes. It has been established that genes with the exon-intron organization have similar tendencies of variation of the lengths of exons and introns with an increase in the number of introns.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
