What is the name for a stretch of non-coding DNA that interrupts the coding sequence of a gene?
It is an intron.
The coding segments of DNA are exons. At transcription, a molecule of messenger RNA (mRNA) is formed that "mirrors" the complete gene, introns included. The cell subsequently edits the mRNA, cutting out the unwanted sections.
There are also introns in genes that code for RNA, such as transfer RNA (tRNA) and ribosomal RNA (rRNA).
Most eukaryotic genes are interrupted by introns, but most prokaryotic genes have none. In the human genome, the gene for the protein dystrophin has 78 introns.
What else can I help you with?
How many amino acids are there in the coding sequence for insulin?
The coding sequence for insulin consists of 110 amino acids.
What are introns and pseudogenes Are they the same?
Introns and pseudogenes are not the same.An intron is a segment of DNA that "intrudes" into or "interrupts" a coding stretch of DNA. Many genes in humans have introns, but bacteria seem to have none. To take an extreme example, the human dystrophin gene has 79 exons (separate coding segments) spread over more than 2.3 million base pairs.A pseudogene is a DNA segment that resembles a functional (coding) gene, but does not itself code for a gene product. It seems likely that pseudogenes arise when a gene is copied within the genome, and one of the copies drifts away from the functional sequence. "Pseudogene" literally means "false gene".
What is the importance of coding in sequence?
Coding sequence is used to build proteins from amino acids. Each amino acid has a specific 3-base sequence known as codons. Since proteins are very important in our lifes and many biochemical processes, the coding sequence is very important. A change in the coding sequence (mutation) may result in the wrong protein being produced. Some incurable human diseases are as a result of changes in coding sequence
When you read a DNA sequencing gel from the bottom to the top is what you read called the coding strand or the non-coding strand?
When reading a DNA sequencing gel from bottom to top, you are reading the sequence of the complementary non-coding strand of DNA. This is because the gel displays the sequence of bands corresponding to the bases in the DNA template strand, which is the non-coding strand.
What is the difference between an intron and exon?
Introns are non-coding segments of DNA that are removed during RNA processing, while exons are coding regions that are spliced together to form the final mRNA transcript. Exons contain the information needed to produce proteins, while introns do not.
What is the name for a stretch of non coding DNA that interrupts the coding sequence of a gene?
introns
What are internal non coding regions of RNA called?
Internal noncoding regions of RNA are called introns. They are segments of an RNA molecule that interrupt the sequence of genes.

The coding sequence for insulin consists of 110 amino acids.

What is the noncoding segement of a gene are cut out of an mRNA transcript?
The noncoding segments of a gene that are removed from an mRNA transcript during post-transcriptional processing are called introns. The remaining coding segments of the mRNA transcript, called exons, are then spliced together to form the mature mRNA that will be translated into a protein.
What are the coding segments of a stretch of eukaryotic DNA?
Exons
What is the significance of noncoding DNA to DNA identification?
Noncoding DNA, also known as junk DNA, does not code for proteins but can contain unique variations that are specific to individuals. By analyzing these variations in noncoding DNA regions, forensic scientists can create a DNA profile for identification purposes, as these variations are highly specific to each person. This can be particularly useful in cases where coding DNA is not available or is not as informative for identification.
Point mutations occur when?
Point mutations occur when a single nitrogen base in the DNA sequence is substituted, inserted, or deleted, leading to a change in the genetic code. These mutations can result in altered protein structure and function, potentially causing genetic disorders or diseases.
What the noncoding segment of a gene are cut out of an mRNA transcript while what are spliced?
The noncoding segments of a gene, called introns, are removed from the mRNA transcript during the process of splicing. The coding segments of a gene, called exons, are spliced together to form the mature mRNA molecule that can be translated into protein.
What are genes a part of?
There are three main parts of a gene. First, the promoter includes when and where the gene should be transcribed. Then, the coding sequence contains the instructions for making a protein. Last, the terminator indicates that the coding sequence is over.
