Nucleotide sequences found in the structural genes of eukaryotes that are non-coding and interrupt the sequences containing information that codes for polypeptide chains. Intron sequences are spliced out of their RNA transcripts before maturation and protein synthesis. (cf. Exons)
DNA sequences that interrupt the protein-coding sequences of a gene (exons) and are eventually spliced out. Only the exons are translated into protein. The function of introns is still being explored.
Noncoding DNA sequences that interrupt the sequences containing instructions for making a protein (exons). Introns are not represented in messenger RNA; only the exons are translated into protein. The function of introns is still being explored.
those intervening pieces of a eukaryotic gene that need to be edited out following transcription
Noncoding regions of eukaryotic genes, which are transcribed into mRNA but are then excised by a process called RNA-splicing. See exon.
Sequences of non-coding bases found in eukaryotic genes. They may make up a large proportion of the total gene length. Introns are spliced out of the RNA transcript during its processing to mRNA.
The sequence of DNA bases that interrupts the protein-coding sequence of a gene; these sequences are transcribed into RNA but are edited out of the message before it is translated into protein.
DNA sequences without instructions for making protein that come between those sequences with instructions for making protein (exons). Introns are not in messenger RNA, and it is not known what they are for.
intervening sequences in a split gene; do not appear in the ultimate RNA product.
in RNA, the sections of the strand that are cut out because it is uneeded; in DNA, A segment with an unknown purpose - accounts for 95% of the cell's DNA
A piece or number of pieces of the DNA of a gene, which after transcription into mRNA is/are cut out of the mRNA. Therefore, introns do not contribute to the translation of the mRNA into the protein product of the gene.
The DNA base sequences interrupting the protein- coding sequences of a gene; these sequences are transcribed into RNA but are cut out of the message before it is translated into protein. Compare exons.
a portion of DNA that lies between the exons. It is spliced out in MRNA and does not get translated into protein.
the noncoding regions of a gene. See exons.
DNA sequences in genes which have no protein-coding function. Other non-coding regions include control sequences and intergenic regions whose functions are unknown.
The non-coding sequences interrupting the protein-coding sequences of a gene; these sequences are transcribed into RNA but are spliced out before it is translated into protein.
