DNA is organized in segments on chromosomes called genes. Humans typically have 46 chromosomes arranged in 23 pairs. Genetics plays a key role in answering each of these questions. For humans ...
Plastic chemicals may harm DNA, as new research reveals how additives disrupt nematode egg formation, suggesting risks to human reproductive health.
A 2017 study published in the journal PLOS Genetics said the chromosome's evolution of palindromes — DNA sequences that read the same forward as backward — and repetitive copies of genes could ...
eLife is a non-profit organisation inspired by research funders and led by scientists. Our mission is to help scientists accelerate discovery by operating a platform for research communication that ...
X inactivation is the dosage compensation mechanism in mammals whereby during embryogenesis of females a single X-chromosome is genetically silenced. Although most genes are subject to X ...
Importantly, McClintock noted that the frequency and timing of variegation and chromosome breakage were linked. Today we also know that transposons constitute a large fraction of the DNA in some ...
our longevity is primarily determined at the moment of conception and is largely reliant on our parents and their genes. The basis behind this theory is that segments of DNA that occur at the end of ...
These fatty acids act like molecular switches, attaching to specific proteins called histones that package our DNA, ultimately affecting which genes get turned on or off. Two byproducts of fiber ...
Summary: Researchers identified variants in the DDX53 gene, located on the X chromosome, as contributors to autism spectrum disorder (ASD). These genetic variants, found predominantly in males, ...
Abdenour Soufi from the University of Edinburgh reveals how transcription factors (TFs)—key proteins that regulate gene activity—navigate DNA and chromatin structures to determine cellular ...
2 X-linked inheritance is determined by a gene on the X chromosome, with X-linked recessive ... which uses fluorescent-labeled DNA probes to assess the complementary DNA sequence of interest ...
