what is a cag repeat?
449707
The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene.

One word answer- YES, question repeats in SSC CGL. Suppose 1 question repeated from the previous year Paper. ... So, If you are planning to study from the previous year papers only then you can get only 4–5 question in the same format.

One of these is called the leading strand, and it is replicated continuously in the 3' to 5' direction. The other strand is the lagging strand, and it is replicated discontinuously in short sections. These sections are called Okazaki fragments, and they are short lengths of DNA.

Some studies have shown that certain types of CAAs can run in families, but doctors have not yet found a solid pattern to say for sure that CAAs may be hereditary. Coronary artery anomalies are found in about 5% of people who undergo cardiac catheterization to find out why they are having chest pain.

ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases.

Microsatellites or STRs are repetitive co-dominant sequences of 2–6 bp of DNA that are present throughout the entire genome. They are often used for identification or fingerprinting of DNA. Microsatellites are amplified by PCR using fluorescently labeled primers and the amplicons are separated using CE.

ACG stands for alternating current generator or something like that.

DNA sequencing is a laboratory technique used to determine the exact sequence of bases (A, C, G, and T) in a DNA molecule. The DNA base sequence carries the information a cell needs to assemble protein and RNA molecules. DNA sequence information is important to scientists investigating the functions of genes.

Chegg.com. What is a CpG island? ... CpG (cytosine-phosphate-guanine) refers to a dinucleotide of Cytosine and Guanine connected via a phosphodiester bond. Island or groups of CpG can be 1000 to 2000 bps (base pairs) long and have a huge number of CpG sites.

VNTR is a small fragment of DNA containing tandemlyy repeated sequence, whose number and length vary among chromosome and individuals. VNTR shows a high level of polymorphism and is specific for different individual, whereas Probe is a small fragment of DNA or RNA used for identification of genes in biological system.

Huntington's disease (HD) is an inherited neurodegenerative disorder caused by an expanded CAG repeat that encodes an abnormally long polyglutamine stretch in the disease protein huntingtin [39]. Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder that occurs sporadically or as a familial disorder.

ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). ... Adenine pairs with thymine, and cytosine pairs with guanine. The sequence of bases in a portion of a DNA molecule, called a gene, carries the instructions needed to assemble a protein.

No particular dementia etiology (degenerative or vascular) predominated in one group over the other. In the TGA group, there was also no evidence of an association between TGA recurrence and cognitive impairment (P=77), cerebrovascular event (P=71), or seizures (P=46).

Repetitive DNA. Repetitive DNA can be divided into two classes: the tandem repetitive sequences (known as satellite DNA) and the interspersed repeats. The term satellite is used to describe DNA sequences that comprise short head-to-tail tandem repeats incorporating specific motifs.
