- DNA Barcoding of plants, animals and microbes is one of the new services offered. (rgcb.res.in)
- When the scientists trained a machine to classify each assortment of microbes from under the gums according to ethnicity, a given bacterial community predicted an individual's ethnicity with 62 percent accuracy. (sciencedaily.com)
- The Microbiology Society is a membership charity for scientists interested in microbes, their effects and their practical uses. (microbiologysociety.org)
Amplification1
- This amplification is necessary because the amount of DNA from a sample might be limited, and PCR ensures there's enough DNA to study. (biologywala.com)
Identify3
- In other cases, we can make sound available for citizen scientists to explore, listen to and identify calls. (cosmosmagazine.com)
- The DNA fingerprinting technique developed by Henry Erlich made it possible for scientists to identify an individual from the DNA in a single hair. (wikisummaries.org)
- Scientists use flipper and passive integrated transponder tags to identify the turtles and keep a record of the number of clutches (nests) each female lays and their success. (noaa.gov)
Profiles3
- DNA profiles are similar to genetic fingerprints. (medgadget.com)
- This principle revolves around the variability of certain DNA regions, specifically the Short Tandem Repeats (STRs), which are integral to creating distinctive DNA profiles for each individual. (biologywala.com)
- The variable nature of STRs is what gives rise to the uniqueness of DNA profiles. (biologywala.com)
Unique2
- Every person has a unique DNA profile, which makes it extremely useful for identifying criminals. (medgadget.com)
- Together they form a unique fingerprint. (lu.se)
Curiosity2
- Many scientists have strong curiosity about reality and strive to use their knowledge to improve the world. (radiosilencebook.com)
- The author mentions three qualities that go into the making of a scientist-a first-rate mind, curiosity, and the will to win for the right reasons. (swastikclasses.com)
Loci1
- By looking at a sufficient number of loci, whose alleles are distributed among the population, a kind of fingerprint can be established. (eff.org)
Genomes1
- The Medusavirus is a nucleocytoplasmic large DNA virus, which belongs to a group of recently discovered eukaryotic viruses with large and complex double-stranded DNA (dsDNA) genomes. (eurekalert.org)
Gather1
- Scientists study sea turtle "fingerprints" to gather clues about their life history, mating strategies, and family groups. (noaa.gov)
Study1
- We also study how the same DNA sequence can give rise to different phenotypes, as observed in various cell types of a single organism. (ccmb.res.in)
Studies2
- Hidden in a hatchling's DNA is its entire family history, including who its mother is, who its father is, and to what nesting population it belongs," says NOAA scientist Peter Dutton, who studies the DNA of endangered leatherback sea turtles . (noaa.gov)
- MRC scientists carried out 2 major studies during the 1970s and early 1980s into mild hypertension (high blood pressure). (ukri.org)
Technique1
- Although challenges and limitations to the use of DNA fingerprinting exist, the widespread implementation of the technique into routine TB prevention and control practices appears scientifically justified. (cdc.gov)
