SNPs (often pronounced “snips”) are single base-pair changes in DNA that occur at specific places in the genome. For example, most individuals carry the C nucleotide at a specific base position in the genome, but in a minority of individuals this...

What are the downsides of being an ecology or evolutionary biology graduate student? The sequencing of the Neanderthal genome has prompted speculation that it might be possible to genetically engineer a living Neanderthal. What ethical issues might arise from this?
Genetic markers have been used in horticulture and conservation biology to identify breeding lines, assess genetic diversity, and examine gene flow. In weed science, analysis of genetic markers is not as common, as the focus often lies in the development of control methods. This is unfortunate, ...
Genetics of obesity: what genetic association studies have taught us about the biology of obesity and its complications.Genome-wide association studies (GWAS) for BMI, waist-to-hip ratio, and other adiposity traits have identified more than 300 single-nucleotide polymorphisms (SNPs). Although the...
The coding sequences of DNA molecule are called exons which carry information required to synthesize proteins. The non-coding sequences, on the other hand, are called 'introns' and these do not supply any relevant genetic information.
This vital role of TNFR2 in normal brain function was also evidenced by Pillai et al., who measured CSF levels of sTNFR2 and evaluated two SNPs in the TNFRSF1B gene in patients with AD. The authors found that CSF levels of sTNFR2 and the specific TNFRSF1B gene variations can serve...
Genomic studies using single-nucleotide polymorphisms (SNPs) have identified more than 100 loci associated with the development of RA. These loci are predominantly involved in the regulation and maintenance of the immune response, emphasizing the complex interaction of the disease with the immune system...
