• Their tiny size and lack of obviousness is only one barrier to discovery: with the development of modern molecular phylogenetic methods in the 1970s came the realisation that most of the world's microbial, and therefore total genetic resource, had yet to be accessed. (scielo.org.za)
  • In a bid to stop "biopiracy," researchers are building a giant database to catalog genetic material from the world's largest rainforest. (japantimes.co.jp)
  • For example, many diseases are associated with single-nucleotide polymorphisms, and performing genome-wide association studies using large collections of samples which represent tens or hundreds of thousands of individuals can help to identify disease biomarkers. (wikipedia.org)
  • Gene therapy treats genetic diseases by giving patients a healthy version of a defective gene. (stjude.org)
  • At the same time technological advances also made it possible for wide sharing of information, so when data was collected, many scientists doing genetics work found that access to data from genome-wide scans collected for any one reason would actually be useful in many other types of genetic research. (wikipedia.org)
  • In affected males, almost all sperm cells have abnormally large and misshapen heads. (nih.gov)
  • The head of the sperm cell contains the male's genetic information that is to be passed on to the next generation. (nih.gov)
  • This additional genetic material accounts for the larger head size of the sperm cell. (nih.gov)
  • Because of the additional genetic material, if one of these abnormal sperm cells combines with an egg cell, the embryo will not develop or the pregnancy will result in miscarriage. (nih.gov)
  • Genetic anomalies, from tiny deletions or substitutions of single bases to large stretches of missing code or even multiple copies of the same code, often crop up in the human genome and, occasionally, can create a disposition to a particular type of disorder. (scientificamerican.com)
  • Then, sufficient copies of each piece of the human genome could be generated so that automatic sequencing machines would have enough material to sequence the DNA. (encyclopedia.com)
  • Virtually no large land animals survived. (skepticalscience.com)
  • Further, as fecal pellet size affected scat detection, juvenile or smaller-sized animals may be less detectable than adult or large animals, which could introduce bias into abundance estimates. (osti.gov)
  • Our results suggest that use of a fixed-width radial search protocol may increase the number of scats detected for wild pigs, or other social ungulates, allowing more robust estimation of population metrics using noninvasive genetic sampling methods. (osti.gov)
  • The condition appears to arise from both genetic and environmental factors, and involves complex autoimmune processes. (medicalnewstoday.com)
  • It is a large, brick-shaped, enveloped virus that ranges in size from 265-295 nm. (wikipedia.org)
  • These results are consistent with our understanding of the population history of Europe and promote Ireland and Scotland as relatively homogenous resources for genetic mapping of rare variants. (blogspot.com)
  • It is what you could call a foot in the door to access the genetic information," said Langowski interpreting his results. (healthcanal.com)
  • The group has been the first to demonstrate that the spool-shaped histone proteins have an active role in opening access to the genetic information. (healthcanal.com)
  • Gene therapy is designed to restore the function of a patient's defective gene by introducing a healthy copy, with the potential to permanently correct a genetic disease. (stjude.org)
