Using the Longman Dictionary of Contemporary English, we may define flank as follows: 1 the side of an animal’s or person’s body that is between the ribs and the hips 2 the army’s side in a fight, or the side of a sports team while they’re competing We were attacked on our left flank, which was a surprise. 3
The DNA sequences that stretch on each side of a certain locus or gene are known as flanking sequences.
What is the meaning of flank?
Defining Flank in Children’s Terms (Entry 2 of 2) 1: to be situated on the outskirts of With two rats on either side of him, the Father Abbot took a step forward.. ― Brian Jacques, author of Redwall 2: to make an assault or threat on the other side We’ve positioned ourselves on the flanks of the opposing forces.
What is the flanking region of a gene?
ACCESSING THE DICTIONARY FROM THE HOME PAGE Region that is surrounded by water A segment of DNA is located just close to the 5′ end of the gene. The promoter is located in the 5′ flanking region of the gene, which may also contain enhancers or other protein-binding sites.
What is the purpose of flank attack?
Due to the fact that a force’s offensive might is focused at its front, flanking is advantageous. As a result, attacking a force’s flank rather than its front is an effective way to concentrate assault in an area where the opponent is least able to focus defensive efforts. Flanking may occur at the tactical, operational, and strategic levels of a conflict as well.
What is the significance of flanking sequence variation?
Flanking sequences appear to be responsible for supramolecular interaction, indicating that the kinase is capable of more than just catalytic activity under CaM control. Advanced Topics in Forensic DNA Typing: Interpretation, by John M. Butler, published in 2015. Flanking region variation can also give rise to alleles that appear to be ″off the ladder.″
What is flank in biology?
Region in the outskirts. (In the field of science, molecular biology) The dna sequences that stretch on each side of a certain locus or gene are known as flanking sequences.
What is flanking sequence in PCR?
PCR reactions need the use of two primers, which are specifically designed to flank the target area in each PCR reaction (region that should be copied). In other words, they are given sequences that will cause them to attach to opposing strands of the template DNA, only at the borders of the area to be copied, rather than the middle of the region.
What is a 5 flanking sequence?
This is a section of DNA that is NOT translated into RNA, but is rather located close to the 5′ end of the gene. There may also be enhancers or other protein binding sites in the 5′-Flanking region, which is where the promoter is located.
Why are flanking regions important?
Regions under control When it comes to defining the pattern and amount of expression of a gene, it is frequently discovered that the gene’s flanking regions are important.
What is a flanking region in DNA?
The 5′ flanking region is a stretch of DNA that is located immediately next to the 5′ end of a gene’s transcript. The promoter is located in the 5′ flanking region of the gene, which may also contain enhancers or other protein binding sites. It is the portion of DNA that is not translated into RNA during the transcription process.
What does flank mean in medical terms?
The term ″flank″ refers to the portion of the human anatomy that is on the side of the body between the ribs and the hip. The term flank is also used to define the side of an animal’s body, which is also known as the side region of the body.
What is a 3 flanking region?
In contrast to the mature mRNA, a portion of DNA close to the 3′ end of a gene is not transcribed, but it is still there.
Is there flanking in 5E?
Fighting when flanked is an optional feature in Dungeons and Dragons 5E that is designed to give combatants additional tactical depth. When a creature and at least one ally are within 5ft of the same opponent on opposing sides of the battlefield, that enemy gets flanked.
What is the function of Taq polymerase?
What is Taq Polymerase, and how does it work? Taq DNA Polymerase, also known as Taq polymerase, is a biological catalyst that, like any other polymerase, is involved in the attachment of nucleotides in the process of DNA synthesis.
Where are introns located?
Introns are found in the genes of most animals and many viruses, and they may be found in a broad variety of genes, including those that produce proteins, ribosomal RNA (rRNA), and transfer RNA. Introns are also found in the genes of bacteria and viruses (tRNA).
What is the function of the 3 UTR?
When it comes to gene expression, the 3′-untranslated region is critical because it influences the localization, stability, export, and translation efficiency of a messenger RNA (mRNA). It comprises a variety of sequences that are important in gene expression, such as microRNA response elements (MREs), AU-rich elements (AREs), and the poly(A) tail, among other components.
How do you find the 5 UTR sequence?
5′ untranslated region (UTR) in eukaryotes is defined as the sequence from the beginning of exon 1 to the nucleotide that is immediately upstream of the start codon. Similarly, the 3’UTR is the nucleotide that is located immediately downstream of the stop codon and continues until the conclusion of the final exon.
What is cDNA in biology?
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule that is made by reverse transcriptase, a DNA polymerase that can utilize either DNA or RNA as a template to create DNA copies of mRNA molecules. From the Encyclopedia of Genetics, published in 2001.
What is TATA box in biology?
A TATA box is a DNA sequence that marks the location of a genetic sequence that may be read and decoded by a genetic sequence reader. It is a form of promoter sequence that tells other molecules when and where transcription should begin to take place. Transcription is a process that results in the production of an RNA molecule from a sequence of DNA.
What are flanking direct repeats?
Terminal repeat sequences (sometimes referred to as flanking or terminal repeats) are sequences that are repeated on both ends of a sequence; for example, long terminal repeats (LTRs) found on retroviruses are one example of this.Direct terminal repetitions are repeated in the same direction as each other, whereas inverted terminal repeats are repeated in the opposite direction of each other.
