Abstract RNA splicing is a fundamental step of gene expression. While constitutive splicing removes introns and joins exons unbiasedly. alternative splicing (AS) selectively determines the assembly of exons and introns to generate RNA variants corresponding to the same transcript. The biogenesis of circular RNAs (circRNAs) is inextricably associated with AS. https://unitedssports.shop/product-category/basketball-accessories-bags/
