Function: Canonical structure of DNA Cruciforms Extruded DNA duplexes with 2 B-DNA stem-loops connected by a four-way junction (see Holliday junction) AT-rich inverted repeats “Extended”—DNA Extended right-handed A-like duplex with Watson–Crick base pairs; 12.2 bp/turn, 3.6–3.7 Å ris...
function. Alternatively, a family of natural genes from one or multiple species can be recombined in a method known as ‘family shuffling’; the rationale for this strategy is that Nature has already selected mutations that are ideal for properprotein foldand function through millions of years of...
DNA Academy is a three-part series designed to introduce the basics of DNA for genetic genealogy and how Y-DNA, X-DNA, mitochondrial and autosomal DNA can be utilized. Each of these different types of DNA serves a different function for genealogists – and reveals different matches and hints...
TEs can insert near regulatory elements, such as promoters, enhancers, or insulators, and disrupt their function. This can result in the misregulation or aberrant expression of genes. Changes in the regulation of critical genes can have profound effects on cellular processes, development, and disease...

The definition of a sex chromosome is not always clear-cut. It is generally applied to a pair of chromosomes on which the sex determination locus resides regardless of whether they are morphologically distinguishable (heteromorphic) and mostly non-recombining, or conversely, morphologically indistinguisha...
For sequences related by evolution, such as those from the same taxonomic unit, these segments are known as conserved regions.They are likely to be responsible for a particular function or provide a needed structural characteristic. As an illustration, Figure 2 shows a GenModel created from the ...
Replacement of one amino acid in a protein by another can seriously affect the protein's biological function.(more) Genetics has shown that mutation is the ultimate source of all hereditary variation. At the level of a single gene whose normal functional allele is A, it is known that ...
correctly recovered just by using these maxima: a) m3, b) m4, c) m5 and d) Es (see also Table 1). The profiles for theLmaxandφmaxare also shown: apparently one can obtain a non-decreasing function of the positions, which means that previous suffixes are embedded in the implanted ...
