a transgene is a gene that is not native to an organism (eg. it is a gene that is transferred from one organism to another)
recombinant DNA is DNA that has essentially been combined with other, different DNA. DNA is double-stranded (the two strands are held together by basepair complementation). during recombination, the strands break apart, thus allowing another strand to bind with either of the original strands:
original strands
DNA you want to insert into the organism (aka. a transgene) ]]
you break apart the original strands | |
and you add your strands |] |]
now you have recombinant DNA, which is what a transgene will be when it has been integrated into an organism. it will (hopefully) be expressed correctly.
(it's sliiightly more complicated than this haha, and the transgene can integrate (recombine) in numerous ways... but that's a solid foundational understanding of the process)
hope this helps!

Recombinant DNA is created by combining DNA from different sources, such as different species, through techniques like genetic engineering. Non-recombinant DNA refers to DNA that has not been modified in this way and only contains genetic material naturally found in an organism.
when a organism is helped or harmed you call it a parasite
The Difference between mutualism And commensalism is that mutualism is a relationship between two species in which both species benefit and Commensalism is a relationship between two organisms in which one organism benefits and the other is unnaffected.
Mutualism is a type of symbiotic relationship in which both organisms benefit from each other. This can involve one organism providing resources or services that the other organism needs in exchange for benefits.
Genetic engineering is the combining of DNA from different species and can only be done in the laboratory. Traditional plant and animal breeding stay within the species to get the desired result.
The term is transgenesis.The product is recombinant DNA, and the resulting organism is transgenic, e.g. a transgenic mouse. But the word "transgenic" is not applied to bacteria.Typical methods of creating recombinant DNA include:* using bacterial plasmids, which are modified and then replaced in bacteria * using a virus as a vector (carrier of modified DNA into a host organism) * microinjection using a micropipette There are other techniques.
It is called Commensalism- a relationship in which one organism benefits from another organism but does not harm it
ecology
This is an example of a parisitic relationship because the organism harms the host.
CommensalismMutualismParasitism
The frequency of recombinant gametes is directly related to the distance between two genes on the same chromosome. The farther apart the genes are, the higher the frequency of recombinant gametes. This is because crossing over events during meiosis are more likely to occur between genes that are further apart, leading to a greater chance of genetic recombination.

Parasitism
An organism is an individual living thing, while a species is a group of organisms that can interbreed to produce fertile offspring. All organisms belong to a species, but a species can consist of many individual organisms.
A mutually beneficial relationship between two biotic (living) organisms is called a symbiotic relationship.
It is a symbiotic relationship.
