An Effective Method for Detecting Y-chromosome Specific Sequences of Circulating Fetal DNA in Maternal Plasma During the First-trimester
Background and Aims: New advances in the use of cell-free fetal DNA (cffDNA) in maternal plasma of pregnant women has provided the possibility of applying cffDNA in prenatal diagnosis as a non-invasive method. One of the applications of prenatal diagnosis is fetal gender determination. Early prenatal determination of fetal sex is required for pregnant women at risk of X-linked and some endocrin...
متن کاملBanded krait minor-satellite (Bkm)-associated Y chromosome-specific repetitive DNA in mouse.
The mouse Y chromosome remains highly condensed in all somatic tissues but decondenses extensively in testis. We have isolated a mouse Y chromosome-specific repeat M34 (11.5 kb) and shown that this is distributed along the Y chromosome except the sex-determining region (the Y short arm) in which GATA repeats are predominantly concentrated. It has 32 copies of GATA repeats in a 2.7 kb fragment. ...
متن کاملSimple repeated sequences in human satellite DNA.
In an extensive analysis, using a range of restriction endonucleases, HinfI and TaqI were found to differentiate satellites I, II and III & IV. Satellite I is resistant to digestion by TaqI, but is cleaved by HinfI to yield three major fragments of approximate size 770, 850 and 950bp, associated in a single length of DNA. The 770bp fragment contains recognition sites for a number of other enzym...
متن کاملChromosome-specific alpha satellite DNA: nucleotide sequence analysis of the 2.0 kilobasepair repeat from the human X chromosome.
The pericentromeric region of the human X chromosome is characterized by a tandemly repeated family of 2.0 kilobasepair (kb) DNA fragments, initially revealed by cleavage of human DNA with the restriction enzyme BamHI. We report here the complete nucleotide sequence of a cloned member of the repeat family and establish that this X-linked DNA family consists entirely of alpha satellite DNA. Our ...
متن کاملDynamic organization of DNA replication in mammalian cell nuclei: spatially and temporally defined replication of chromosome-specific alpha-satellite DNA sequences
Five distinct patterns of DNA replication have been identified during S-phase in asynchronous and synchronous cultures of mammalian cells by conventional fluorescence microscopy, confocal laser scanning microscopy, and immunoelectron microscopy. During early S-phase, replicating DNA (as identified by 5-bromodeoxyuridine incorporation) appears to be distributed at sites throughout the nucleoplas...
