Alu family. The Alu family is a family of repetitive elements in primate genomes, including the human genome. Modern Alu elements are about 300 base pairs long and are therefore classified as short interspersed nuclear elements (SINEs) among the class of repetitive DNA elements. The typical structure is 5' - Part A - A5TACA6 - Part B - PolyA Tail - 3', where Part A and Part B …

Huntington's disease is a neurodegenerative disorder which is due to the expansion of repeated trinucleotide sequence CAG in exon 1 of the huntingtin gene (HTT).This gene is responsible for encoding the protein huntingtin which plays a role in preventing apoptosis, otherwise known as cell death, and repair of oxidative DNA damage. In Huntington's disease the expansion of the …

A computer program is a sequence or set of instructions in a programming language for a computer to execute.Computer programs are one component of software, which also includes documentation and other intangible components.. A computer program in its human-readable form is called source code.Source code needs another computer program to execute …

In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers. It is a fundamental building block of many types of computing circuits, including the central processing unit (CPU) of computers, FPUs, …

A computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically.Modern computers can perform generic sets of operations known as programs.These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the …

A telomere (/ ˈ t ɛ l ə m ɪər, ˈ t iː l ə-/; from Ancient Greek τέλος (télos) 'end', and μέρος (méros) 'part') is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes.Although there are different architectures, telomeres, in a broad sense, are a widespread genetic feature most commonly found in eukaryotes.

Une séquence Alu est un court fragment d'ADN appartenant à la famille des éléments nucléaires dispersés courts ou SINE (short interspersed nuclear element).Elles sont caractérisées par la présence d'un site de restriction de l'endonucléase de restriction AluI (5'-AGCT-3') [1].Elle provient de la rétrotransposition de l'ARN 7SL (Cet ARN non codant fait normalement partie du …

x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972. It is used to produce object code for the x86 class of processors.. Regarded as a programming language, assembly is machine-specific and low-level.Like all …

Z-DNA is one of the many possible double helical structures of DNA.It is a left-handed double helical structure in which the helix winds to the left in a zigzag pattern, instead of to the right, like the more common B-DNA form. Z-DNA is thought to be one of three biologically active double-helical structures along with A-DNA and B-DNA

A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" and "1" ().. The base-2 numeral system is a positional notation with a radix of 2.Each digit is referred to as a bit, or binary digit.Because of its straightforward implementation in digital electronic circuitry …
