LINEs insert themselves into regions of the eukaryotic genome that are rich in bases AT. At AT regions LINE uses its nuclease to cut one strand of the eukaryotic double-stranded DNA. The adenine-rich sequence in LINE transcript base pairs with the cut strand to flag where the LINE will be inserted with hydroxyl groups.
It is a necessary condition that an object has four sides if it is true that it is a square; conversely, the object being a square is a sufficient condition for it to be true that an object has four sides. [4] Four distinct combinations of necessity and sufficiency are possible for a relationship of two conditions. A first condition may be:
The most common technique to add inserts to desired sequences is the use of homologous recombination. [5] This technique has a specific requirement where the insert can only be added after it has been introduced to the nucleus of the cell, which can be added to the genome mostly during the G2 and S phases in the cell cycle. [6]
For example, LINEs and SINEs in rodents and primates show very strong homology at the insertion-site motif. [24] Such evidence is a basis for the proposed mechanism in which integration of the SINE transcript can be co-opted with LINE-coded protein products.
The motion of a particle located at position can be described by the Smoluchowski's limit of the Langevin equation: [11] [12] = + (), where is the diffusion coefficient of the particle, is the friction coefficient per unit of mass, () the force per unit of mass, and is a Brownian motion.
Multiple test procedures developed using the graphical approach for constructing and illustrating multiple test procedures [2] are a subclass of closed testing procedures. See also [ edit ]
A line of credit is a credit facility extended by a bank or other financial institution to a government, business or individual customer that enables the customer to draw on the facility when the customer needs funds. A financial institution makes available an amount of credit to a business or consumer during a specified period of time.
The human genome contains an estimated 100,000 truncated and 4,000 full-length LINE-1 elements. [10] Due to the accumulation of random mutations, the sequence of many LINEs has degenerated to the extent that they are no longer transcribed or translated. Comparisons of LINE DNA sequences can be used to date transposon insertions in the genome.
