Practically, cycle regulation, chromosome stability and epigenetic F9 cells allow for the efficient metabolic labelling of the modification, in both mouse and human oocytes SILAC reference in vitro, overcoming the difficulty of directly labelling oocytes in vivo. (gotomydoctor.com)

Each chromosome contains many genes, the basic physical and functional units of heredity. (jainworld.com)
These chromosomes carry heredity factors or genes. (jainworld.com)

Normally, these genes act like brakes that help stop abnormal cell growth. (nextnature.net)

It must also be taken into consideration that while most tumours arising in BRCA1 mutation carriers have typical pathology, a sizeable minority do not. (biomedcentral.com)

Claim 16: A pair of single-stranded DNA primers for determination of a nucleotide sequence of a BRCA1 gene by a polymerase chin reaction, the sequence of said primers being derived from human chromosome 17q, wherein the use of said primers in a polymerase chain reaction results in the synthesis of DNA having all or part of the sequence of the BRCA1 gene. (patentdocs.org)
Claim 17: The pair of primers of claim 16 wherein said BRCA1 gene has the nucleotide sequence set forth in SEQ ID NO:1. (patentdocs.org)

Realizing the benefits of human genetics and genomics research for people everywhere. (ashg.org)
Dr. King is known worldwide for her major accomplishments in human genetics. (ashg.org)
Mary-Claire King has changed the lives of many individuals, as well as the course of research in human genetics," said Joann Boughman, PhD, executive vice president of ASHG. (ashg.org)
She has also served on the Editorial Board of ASHG's scientific journal, The American Journal of Human Genetics (AJHG). (ashg.org)

Analysis of syndromic DNA using an oligonucleotide microarray (Agilent 4 x 180K) demonstrated the characteristic deletion in 15q11.2-q13 (chromosome 15) found in patients with Prader-Willi syndrome. (enzolifesciences.com)

Isolation of the BRAC1 and BRAC2 genes opened the door for Myriad to determine the typical sequence of DNA nucleotides within those genes. (pamedmal.com)

Here we tracked micronucleated chromosomes with live-cell imaging and show that acentric fragments cluster in close spatial proximity throughout mitosis for asymmetric inheritance by a single daughter cell. (nature.com)
The stochastic inheritance of chromosome fragments by both newly formed daughter cells could in part contribute to the alternating DNA copy-number states that are characteristic of chromothripsis 2 . (nature.com)
The process of inheritance is based upon the process in which the offspring receives one of each gene pair from each parent. (jainworld.com)
Whereas multiple - factor inheritance involves the action of several genes. (jainworld.com)

Two articles describe tools for the detection of large-scale structural rearrangements in individual chromosomes. (hum-molgen.org)

However, direct evidence of the connections between ATG gene dysfunction and human diseases has emerged only recently. (nature.com)
This review focuses on the role of macroautophagy (hereafter referred to as autophagy) in human diseases. (nature.com)
However, these experimental results do not directly demonstrate that defects in autophagy contribute to pathogenesis of human diseases. (nature.com)
Some endure the same chronic diseases that humans do, while others appear to be naturally resistant. (uclahealth.org)
Her discovery of BRCA1 revolutionized the study of numerous other common inherited diseases. (ashg.org)

A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene. (genome.gov)

Mitotic clustering facilitates the reassembly of acentric fragments into rearranged chromosomes lacking the extensive DNA copy-number losses that are characteristic of canonical chromothripsis. (nature.com)
An individual with dominant gene, for a particular characteristic, displays that characteristic whether only one or both genes in the pair are dominant. (jainworld.com)
If a gene is recessive, however, the characteristic associated with it does not show up unless both genes in the gene pair are recessive. (jainworld.com)

Thus, distinct patterns of chromothripsis can be explained by the spatial clustering of pulverized chromosomes from micronuclei. (nature.com)

In the nineteenth and twentieth centuries, the development of new microscopic and molecular techniques, including DNA sequencing, enabled scientists to confirm the hypothesis that chromosomes determine the sex of developing organisms. (asu.edu)
A mainstream hypothesis is that maternal ageing of oocytes has its roots in gene transcription. (gotomydoctor.com)

Chromosomes are pairs and each chromosome contain 1000 or so genes that also occur in pairs. (jainworld.com)

In an adult organism, the genes on the Y-chromosome help produce the male gamete, the sperm cell. (asu.edu)

Without doubt, the first human transforming gene, and more broadly, oncogenes and anti-oncogenes, had been previously theorized by Theodor Boveri. (jcancer.org)

Mechanistically, the CIP2A-TOPBP1 complex prematurely associates with DNA lesions within ruptured micronuclei during interphase, which poises pulverized chromosomes for clustering upon mitotic entry. (nature.com)
Mechanistically, (xeno)estrogens triggered centrosome amplification by inducing centriole overduplication that leads to transient multipolar mitotic spindles, chromosome alignment defects, and mitotic laggards. (bvsalud.org)
