Web22 Jul 1997 · One side holds that introns were used to assemble the first genes, an “introns-early” view ( 1, 2 ), and the other side maintains that introns were added during evolution to break up previously continuous genes, an “introns-late” view ( 3, 4 ). WebA hereditary disease is inherited as an autosomal recessive trait. The wild-type allele of the disease gene produces a mature mRNA that is 1250 nucleotides (nt) long. Molecular analysis shows that the mature mRNA consists of four exons that measure 400 nt (exon 1), 320 nt (exon 2), 230 nt (exon 3), and 300 nt (exon 4). licensed insurance agent salary florida https://mondo-lirondo.com
