Exempel på hur man kan använda INTRONS i en mening

• An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing.
• It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions).
• Some non-coding regions appear to be mostly nonfunctional, such as introns, pseudogenes, intergenic DNA, and fragments of transposons and viruses.
• alt=Drawing of a gene showing kinds of defects (missing promoter, start codon or introns, premature stop codon, frameshift mutation, partial deletion).
• They are contributors to the development of penicillin, the discovery of the citric acid cycle, the investigation of high-speed chemical reactions, the discovery of introns in eukaryotic DNA, the discovery of fullerene, and the development of molecular machines.
• While these means of transcriptional regulation also exist in eukaryotes, the transcriptional landscape is significantly more complicated both by the number of proteins involved as well as by the presence of introns and the packaging of DNA into histones.
• If, however, it did detect the X-factor, it would begin inserting introns into the transcription codings of the victim's mutant RNA, the process commonly being triggered after the patient used their powers for the first time after contracting the disease.
• In eukaryotic cells the mature mRNA is already spliced, hence the cDNA produced lacks introns and can be readily expressed in a bacterial cell.
• In the context of gene finding, the start-stop definition of an ORF therefore only applies to spliced mRNAs, not genomic DNA, since introns may contain stop codons and/or cause shifts between reading frames.
• Like in other programs, the data flow in LGP can be modeled as a graph that will visualize the potential multiple usage of register contents and the existence of structurally noneffective code (introns) which are two main differences of this genetic representation from the more common tree-based genetic programming (TGP) variant.
• Many regions of the genome (exons, introns, intergenic regions) normally contain trinucleotide sequences, or repeated sequences of one particular nucleotide, or sequences of 2, 4, 5 or 6 nucleotides.
• MCM6 produces, by alternative splicing, 3 different transcripts, all with introns, putatively encoding 3 different protein isoforms.
• The MOG "primary nuclear transcript … is 15,561 nucleotides in length" and, for humans, it has eight exons which are "separated by seven introns".
• Such processing is vital for the correct translation of eukaryotic genomes because the initial precursor mRNA produced by transcription often contains both exons (coding sequences) and introns (non-coding sequences); splicing removes the introns and links the exons directly, while the cap and tail facilitate the transport of the mRNA to a ribosome and protect it from molecular degradation.
• 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.
• In addition to the well recognized role of NMD in removing aberrant transcripts, there are transcripts that contain introns within their 3' untranslated regions (UTRs).
• The action of snRNPs is essential to the removal of introns from pre-mRNA, a critical aspect of post-transcriptional modification of RNA, occurring only in the nucleus of eukaryotic cells.
• During their evolution where they have adapted to their environment and shrunk in size, they have lost least seven and possibly as many as ten percent of their Hox genes (about 15–20 percent of the total amount) and much of their transposons, and their introns are much reduced.
• Enhancers are CREs that influence (enhance) the transcription of genes on the same molecule of DNA and can be found upstream, downstream, within the introns, or even relatively far away from the gene they regulate.
• The genomic coding region of this protein consists of 13 kilobytes of genetic information with five exons that are split by four introns in the gene.
