Exempel på hur man kan använda INTRON i en mening

• An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product.
• In a study that used mitochondrial and nuclear intron DNA, the black-throated loon was found to be sister to a clade consisting of the Pacific loon and two sister species, the common loon and the yellow-billed loon.
• However, sometimes the RNA within the intron acts as a ribozyme, splicing itself without the use of a spliceosome or protein enzymes.
• These results notwithstanding, analysis of mtDNA cytochrome b and NADH dehydrogenase subunit 2 as well as nuclear β-fibrinogen intron 7 sequence data shows that Swainson's thrush is the most ancient North American species of its genus; it is not closely related to other Catharus and the outward similarities with the other North American species are due to convergent evolution.
• The organization of the SELPLG gene closely resembles that of CD43 and the human platelet glycoprotein GpIb-alpha both of which have an intron in the 5-prime-noncoding region, a long second exon containing the complete coding region, and TATA-less promoters.
• Molecular phylogenetics of Lentibulariaceae inferred from plastid rps16 intron and trnLF DNA sequences: implications for character evolution and biogeography.
• A 2010 study by Delton Hanson and colleagues used DNA sequence data from the mitochondrial gene cytochrome b (Cytb) and two nuclear markers, exon 1 of the interphotoreceptor retinoid-binding protein gene (Rbp3) and intron 2 of alcohol dehydrogenase gene 1 (Adh1-I2) to study relationships among populations of the marsh rice rat and O.
• Certain silencers can be found downstream of a promoter located within the intron or exon of the gene itself.
• Complete splicing of the introns produces the transposase enzyme, while alternative partial splicing of introns 1 and 2, leaving only intron 3 in the mRNA transcript, encodes the P element repressor.
• Sequencing has revealed many different mutations that can account for Type 1, including missense mutations, nonsense mutations, a duplicated set of 4 base pairs in exon 3, and a single thymine insertion in intron 4.

• However, Lerner and Mindell (2005), based on the molecular sequence from two mitochondrial genes and one nuclear intron, indicated a previously unsuspected close relationship of the bateleur with similarly "aberrant" but extremely different, in nearly every respect of appearance and life history, member of the Circaetinae, the Philippine eagle (Pithecophaga jefferyi).

• The first exon corresponds to intron 30 and the remainder of the transcript corresponds to the last two exons of the gene.
