Why dont food chains occur often in nature?
Food chains do not occur often in nature because, many organisms do specialize in their diets.
What are animals that contain foreign DNA called?
Animals that contain foreign DNA are called transgenic or genetically modified organisms (GMOs). This DNA is often added to confer specific traits, such as disease resistance or improved growth characteristics.
When is an organism considered transgenic?
An organism is considered transgenic when it has been genetically modified to contain DNA from a different species. This is typically achieved through techniques such as recombinant DNA technology, where specific genes are introduced into the organism's genome. Transgenic organisms are often used in research, agriculture, and medicine to study gene function, produce genetically modified crops, or develop new therapies.
Splicing DNA from two different organisms produces a new DNA segment called?
When DNA contains parts from two or more organisms it is recombined. Recombinant DNA is often used in genetic engineering. A natural process of DNA recombination is called sexual reproduction.
Which metals are not very reactive and occur in a free state in nature?
Gold, silver, and platinum are examples of metals that are not very reactive and occur in a free state in nature. These metals are often found in their pure form, which makes them relatively easy to mine and extract.

What are genetically modified organism?
GMOs are transgenic organisms. They were created in a lab by taking a gene from one organism (often a bacteria) and inserting it into another organism (often corn or soy, but other varieties, too).
How does the process of making transgenic organisms differ from crossbreeding?
Transgenesis is much like gene therapy in that both transform cells for a specific purpose. (4)However, gene therapy targets only certain cells in order to cure a defect in them, transgenesis seeks to produce an entirely modified organism by incorporating the transgene into all the cells of the mature organism and changing the genomes.

How is biotechnology used in creating or in the upkeep of a transgenic organism?
Gene therapy is one form of biotechnology which is used in the creation and upkeep of transgenic organisms. Often used in an effort to correct genetic errors such as metabolic errors which cause diseases to be inherited between generations of organisms. Through the use of gene therapy, some of these errors can be corrected and therefore cure or lessen the effects of the genetic defects.
How is the word transgenic related to GMO?
GMOs are transgenic. A gene is removed from one organism (often a bacteria) and forced into the DNA of another organism (often corn or soy), which is what transgenics is: mixing one species with another.
What is the purpose of the activity Transgenic Manipulation?
The purpose of transgenic manipulation is to modify an organism's genetic material by introducing foreign genes to observe the effects of the gene expression. This activity is often used in research to study gene function, develop models of human diseases, and produce organisms with desired traits, such as increased crop yield or resistance to pests.
Does respiration occur continuously in the cells of all organisms and often involve the exchange of gases?
Yes, it does.
What are 6 seasonal fires that occur and ways to prevent them?
Forest fires are often "seasonal" in nature.
How does the phenomenon of glowing grass occur in nature?
The phenomenon of glowing grass occurs in nature due to bioluminescent organisms, such as certain types of fungi or bacteria, that emit light as a result of a chemical reaction within their cells. This light emission is often seen in dark or low-light environments and can create a visually striking effect.
What is the process of making a genetically modified organism in a lab?
Contrary to the common understanding of the word, the process which we use to create transgenic organisms is called "cloning". This doesn't refer to copying an organism as often believed. Cloning as scientists mean it refers to creating DNA which does not naturally occur in any organisms. This is also called transgenic DNA.To make a genetically modified organism, we need:transgenic DNA - made by cloningan organismThe transgenic DNA of course needs to be made for a specific purpose. Depending on how big it needs to be, it can be made in different ways. Very small stretches of DNA can be synthesised chemically. Larger bits of DNA are usually made by extracting a cell's DNA and then using a technique called polymerase chain reaction (PCR) to take only one particular bit of the DNA out. We then use restriction enzymes and ligase to cut and paste different bits of DNA together. Usually, the end product will be a plasmid.The finished plasmid (transgenic DNA) then needs to be introduced into the target organism - and there are different ways of doing it for every type of organisms. Some bacteria for example will simply take up plasmids and integrate them into their own DNA without a complicated process around it being necessary. For bigger organisms like animals, it's very difficult - usually impossible - to modify an already living organism. For these, the only option is usually to take an oocyte (egg cell, e.g. a flower seed) and introduce the plasmid into it. If the egg survives this procedure and develops (which is very difficult to achieve), the resulting organism will be transgenic, or genetically modified.
