Fluorescence in situ hybridization FISH can be used to detect directly the presence of the suspect on small samples of patient's tissue. FISH can also be used to compare the genomes of two biological species, to deduce evolutionary relationships. A similar hybridization technique is called a zoo blot. Bacterial FISH probes are often primers for the 16s rRNA region. FISH is widely used in the field of microbial ecology, to identify microorganisms.

How can you tell whether a compound is organic or not? Confidence votes 9.2K. Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.

Indicator Species Indicator species can also be used as measures of environmental quality. For example, many species of lichens are very sensitive to toxic gases, such as sulfur dioxide and ozone. These species (actually, lichens are a symbiosis between a fungus and an alga) have been monitored in many places to study air pollution.

Unicellular organism You can observe the larger unicellular organisms by using a compound microscope. Bacteria just appear as dark dots. To gather unicellular organisms for observation, one can place a cover slip on the surface of pond water, and leave it overnight.

10 Ways to Identify An Insect When identifying an insect, the shape of the antennae may be a clue to what it is. Insect antennae come in a variety of forms, and are an important characteristic to examine when trying to identify an insect. Some insects, like Proturans, lack antennae.

- Taxonomy is the classification of organisms. Although fungi are similar to plants in many ways, they do not have chlorophyll, the green pigment that enables plants to make their own food with the aid of sunlight (photosynthesis). Fungi release digestive enzymes that decompose things around them, turning them into food.any fungi play a crucial role in decomposition (breaking things down) and returning nutrients to the soil. They are also used in medicine, an example is the antibiotic penicillin, as well as in industry and food preparation.

- To identify the short DNA sequences used in DNA fingerprinting. To identify genes from one species that are similar to those of another species. Most genes are remarkably similar in sequence from one species to another, so for example a gene probe for a mouse gene will probably anneal with the same gene from a human.

- The largest Disney World theme park is Animal Kingdom. It can fit EPCOT and the Magic Kingdom comfortably in it's space (which is over 500 acres!) Visitors, though, usually do…n't get to see all the space available (unless you go on the Safari ride), because most of it is for animal conservation.

What Is a Taxonomic Key? Also called a  dichotomous key, a taxonomic key gives users a systematic and reproducible way to identify items and organisms. It is used for a variety of purposes, such as identifying unknown organisms to a certain taxonomic level (e.g. family, genus and species) and identifying rocks or minerals.

- One approach analyzes nuclear DNA and is useful in identifying someone who is alive or has died only recently. This is the technique used to incriminate (or exonerate) suspects of crimes and in paternity testing. It's also the one used to identify the remains of victims of the September 11th attacks.

- DNA is the most powerful tool available for identification in forensic investigations. Because of its ability to link physical evidence found at a crime scene to a single person, it is often referred to as a “digital fingerprint.” This method is so precise that it can ensure pinpoint accuracy, down to one in a billion.

DNA profiling DNA is the most powerful tool available for identification in forensic investigations. Because of its ability to link physical evidence found at a crime scene to a single person, it is often referred to as a “digital fingerprint.” This method is so precise that it can ensure pinpoint accuracy, down to one in a billion.NA databases make it possible for law enforcement crime laboratories to electronically search and compare collected DNA profiles to crime scene evidence. In the United States, the Combined DNA Index System (CODIS) links all local, state, and national databases and contains more than 5 million records.

Fluorescence in situ hybridization General process of fluorescent in situ hybridization (FISH) used for bacterial pathogen identification. First, an infected tissue sample is taken from the patient. Then an oligonucleotide complementary to the suspected pathogen’s genetic code is synthesized and chemically tagged with a fluorescent probe.

Organism An organism refers to any individual living thing that can react to stimuli, reproduce, grow, and maintain homeostasis. It can be a virus, bacterium, protist, fungus, plant or an animal. The earth is home to various organisms and these organisms can be classified taxonomically.
