What is the transcribed region?
This is the part of the gene’s sequence that is used to direct the synthesis of an RNA molecule, known as the transcribed region or a transcript. Within the transcribed region is the region of the RNA that actually encodes the polypeptide, through the process of translation – this is known as the coding region.
What is the transcribed region of DNA?
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
What is the difference between the regulatory region and the transcribed region?
The transcribed region might be described as a gene, cistron, or operon. Regulatory regions in the DNA which control initiation may include the “core promoter” where the basal transcription machinery binds, the “core promoter proximal region” where regulatory factors other than the basal machinery bind.
How much of the genome is transcribed?
And many bases are simply places where chemical modifications serve to silence stretches of our chromosomes. ENCODE’s results are changing how scientists think about genes. It found about 76% of the genome’s DNA is transcribed into RNA of one sort or another, way more than researchers had originally expected.
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.
What is produced in translation?
The molecule that results from translation is protein — or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. Transfer RNA binds to amino acids and drags them over to the messenger RNA strand on the ribosome. …
What is the role of regulatory region?
Regulatory region: A region of a chromosome that controls gene expression. In terms of DNA, it is a regulatory sequence.
What percent of the genome is transcribed into RNA?
A transcriptome represents that small percentage of the genetic code that is transcribed into RNA molecules — estimated to be less than 5% of the genome in humans (Frith et al., 2005). The proportion of transcribed sequences that are non-protein-coding appears to be greater in more complex organisms.
How many transcripts do humans have?
Although there are fewer than 22,000 protein coding genes known in the human genome, they are transcribed into over 140,000 different transcripts (Ensembl release 66 ), over 65% of which have protein coding potential and thus may contribute to protein diversity.
Is the 5 UTR transcribed?
The 5′ UTR begins at the transcription start site and ends one nucleotide (nt) before the initiation sequence (usually AUG) of the coding region. In prokaryotes, the length of the 5′ UTR tends to be 3–10 nucleotides long, while in eukaryotes it tends to be anywhere from 100 to several thousand nucleotides long.
