Expandable DNA Repeat and Human Hereditary Disorders
Background & Aims: Nearly 30 hereditary disorders in humans result from an increase in the number of copies of simple repeats in genomic DNA, including fragile X syndrome, myotonic dystrophy, Huntington’s disease, and Friedreich’s ataxia. One the most frequently occurring types of mutation is trinucleotide repeat expansion. The present study was conducted with the aim of investigating the cause...
متن کاملThe centromere-kinetochore complex: a repeat subunit model
The three-dimensional structure of the kinetochore and the DNA/protein composition of the centromere-kinetochore region was investigated using two novel techniques, caffeine-induced detachment of unreplicated kinetochores and stretching of kinetochores by hypotonic and/or shear forces generated in a cytocentrifuge. Kinetochore detachment was confirmed by EM and immunostaining with CREST autoant...
متن کاملAlgebra 819 - Homework 6
(a) Let ¦ : V × S → V, (v, s) → v ¦ s be a function. Define ¦op : Sop × V → V, (s, v) → v ¦ s. Then ¦ is an R-linear right action of S on V if and only if ¦op is an R-linear action of Sop on V . (⇒) Suppose ¦ is an R-linear right action of S on V . By definition, for all s, t∈ S, u, v∈ V and r∈ R we have (i) v ¦ (st) = (v ¦ s) ¦ t (ii) v ¦ e = v (iii) (u + v) ¦ s = u ¦ s + v ¦ s (iv) (rv) ¦ s =...
متن کاملIntroducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA
Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...
