Difference Between UTR and Intron

The key difference between UTR and intron is that UTR is a non-coding nucleotide sequence which is included in the mature mRNA sequence while intron is a sequence that is not included in the mature mRNA molecule. UTR or untranslated region is a non-coding sequence which is found in the mRNA molecule.

Are introns UTR?

The reason why introns are not considered untranslated regions is that the introns are spliced out in the process of RNA splicing. The introns are not included in the mature mRNA molecule that will undergo translation and are thus considered non-protein-coding RNA.

Is UTR part of exon?

In protein-coding genes, the exons include both the protein-coding sequence and the 5′- and 3′-untranslated regions (UTR). ... Exonization is the creation of a new exon, as a result of mutations in introns.

What is a UTR in biology?

A genomic DNA sequence that is not translated into an RNA sequence.

Is an intron a codon?

The main thing to remember is that exon and introns are features of DNA, whereas codons are features of RNA. ... By definition, exons and introns are sequences in a protein-coding gene region of a double-stranded DNA molecule (dsDNA) that are expressed as proteins, or intervening sequences not so expressed.

Is the 5 UTR transcribed?

The 5′ UTR has been found to interact with proteins relating to metabolism, and proteins translate sequences within the 5′ UTR. In addition, this region has been involved in transcription regulation, such as the sex-lethal gene in Drosophila. Regulatory elements within 5′ UTRs have also been linked to mRNA export.

What is the function of 3 UTR?

3' untranslated regions (3' UTRs) of messenger RNAs (mRNAs) are best known to regulate mRNA-based processes, such as mRNA localization, mRNA stability, and translation.

Is the 3 UTR transcribed?

In molecular genetics, the three prime untranslated region (3′-UTR) is the section of messenger RNA (mRNA) that immediately follows the translation termination codon. ... During gene expression, an mRNA molecule is transcribed from the DNA sequence and is later translated into a protein.

Is 5 UTR present in mature mRNA?

The resultant mature mRNA, in eukaryotes, has a tripartite structure consisting of a 5' untranslated region (5' UTR), a coding region made up of triplet codons that each encode an amino acid and a 3' untranslated region (3' UTR).

Is the promoter in the 5 UTR?

Essential promoter elements are located within the 5' untranslated region of human insulin-like growth factor-I exon I.

What does UTR stand for?

Unique Taxpayer Reference numbers (or UTRs) are 10-digit codes that uniquely identify you or your business. They're used by HMRC whenever they're dealing with your tax.

What is meant by 5 UTR and 3 UTR?

5' UTR is the portion of an mRNA from the 5' end to the position of the first codon used in translation. The 3' UTR is the portion of an mRNA from the 3' end of the mRNA to the position of the last codon used in translation.

Which RNA has shortest lifespan?

So, the correct answer is 'mRNA'
