In your opinion, is it possible for different species to exchange genes?

Because there is reproductive isolation between different species.

Reproductive isolation: Individuals of different populations are unable to mate or are sterile or unable to produce reproductive offspring, resulting in no gene exchange between populations.

At present, in addition to the loss of habitat of species, the harm of alien species is also known as "biological invasion".

is the cause of the world's biodiversity.

The loss of the most concerning thing. The English "biological invasion", also abbreviated as "bio-invasion", is generally translated as "biological invasion" in China, which refers to the departure of organisms from their original places of existence (country, region, ecosystem).

The process of spreading to another environment through natural (air currents, storms, ocean currents, etc.) or man-made means, harming the ecosystems, biodiversity, production of agriculture, forestry, animal husbandry and fisheries, and human health in the invasion area, resulting in economic losses and ecological disasters. As for the term "alien invasive species", some domestic literature has translated it as "invasive alien species". <>

Ecological studies have shown that a successful invasive alien species generally goes through several stages of survival, establishment, and reproduction. The competition between invasive alien species and indigenous species, when resources are limited, leads to the interaction between individuals due to their common needs, which leads to the reduction of the viability, growth and reproduction of the individuals being studied. The ecological consequences of the "invasion" of alien species, and the translation of the word "invasion" based on these consequences, are roughly as follows:

1. Competition and occupation of the ecological niche of indigenous species: Alien species show strong viability and successful invasion in their invaded environment, which is mainly attributed to more suitable environmental conditions and the evasion of natural herbivorous natural enemies. Therefore, some dictionaries also translate "invasion" as "invasion, invasion (referring to the mass growth of animals and plants transplanting other areas)", but there are also translations as "invasion".

2. Allelopathic effects of invasive alien species: There are many factors that determine the successful invasion of an ecosystem by an alien species, among which the allelopathic substances released by alien species into the environment during the invasion process are an important aspect that leads to the success of its invasion. After the alien species invade the ecosystem, they continue to release allelopathic substances into the environment, inhibit the growth of neighboring plants, and obtain more sunlight, nutrients, water and space by themselves, so the alien species form a single dominant species in the ecosystem, which reduces the local biodiversity and habitat diversity, and poses a great threat to the environment.

This phenomenon is also a bit like a biological attack, so some dictionaries translate the word "invasion" as "invasion". <

Gene exchange is the recombination of genes, the same species, different species can be (offspring are generally sterile, because the offspring have been isolated from the species of both parents (reproductive isolation)).

Gene exchange between species is judged based on whether the genes of one species can be expressed normally in another species (i.e., transcribed and translated into the corresponding proteins). cDNA libraries are built based on reverse transcription of mRNA sequences, in which the preserved genes continuously encode the corresponding amino acids in any species, resulting in the synthesis of normal proteins.

The vast majority of organisms share a set of genetic code). Therefore, gene exchange between different species can be carried out through cDNA libraries. But genomic libraries are built by extracting DNA directly from an organism.

Whereas, the genetic structure of prokaryotes is different from eukaryotes. The genes of prokaryotes are continuous, and all of them can code for proteins. But the genes of eukaryotes are discontinuous and are divided into exons and introns.

Only introns can code for proteins, while introns are staggered with exons. So in the genes of eukaryotes, the region that codes for the protein is not continuous. Therefore, the genes of prokaryotes can be expressed normally between prokaryotes and eukaryotes, so that gene exchange between species can take place.

However, genes of eukaryotes can only be expressed normally in eukaryotes through eukaryotic mechanisms that are unique to eukaryotes, but not in prokaryotes. Therefore, genomic libraries can only carry out some gene exchanges between species. That is, prokaryotic-prokaryotic, eukaryotic-eukaryotic, prokaryotic-eukaryotes can communicate with each other, but eukaryotic-prokaryotes cannot communicate with each other.

No, brother, the genes of eukaryotes are divided into introns and exons, but it should be exons that can code for proteins, right?

There is a complex interrelationship between genes and genes, genes and gene products, and genes and the environment, and this interrelationship forms an intricate regulatory network that precisely regulates the traits of organisms.

Hello, it is a pleasure to serve you and give you the following answer: No. Species communication refers to the relationship between multiple species, such as interactions, symbiosis, synergies, competition, and so on.

The reason for the problem of species exchange is mainly due to human activities, such as forestry development, mining, marine fishing, etc., which disrupt the balance of the ecosystem and lead to changes in the relationship between species. Methods and practices to address the problem of species communication:1

Strengthen the protection of wild animals and their environment, and avoid indiscriminate deforestation. 2.Pay attention to the maintenance of the ecosystem and maintain the balance of the ecosystem.

3.Strengthen the conservation of biodiversity so that the relationship between species can be stabilized. 4.

Avoid human intervention to prevent changes in the relationship between species. 5.Strengthen scientific research, gain a deeper understanding of the relationship between species, identify problems in a timely manner, and take timely action.

Teaching experience: Species communication is an important part of the ecosystem, which can maintain the balance of the ecosystem and provide the basis for the conservation and sustainable development of biodiversity. Therefore, we need to strengthen the study of species communication and actively take effective measures to protect the relationship between species to maintain the balance of the ecosystem.

Personal tip: In practice, it is necessary to actively explore the relationship between species, strengthen their scientific research capabilities, and master more knowledge about species communication, so that they can detect problems in time and take timely actions to protect the relationship between species and maintain the balance of the ecosystem.

Similarities: are the same substances: DNA and RNA or DNA or RNA

It serves the same purpose: to carry genetic information.

RNA is inherited from the past.

Differences: The way of inheritance is different, depending on the species.

In fact, the meaning of animals is very broad, including protozoa, sponges, coelenterates, flattened animals, nematozoa, annelids, molluscs, arthropods, echinoderms, and chordates. So the way of inheritance is not exactly the same.

The more obvious difference is chloroplasts.

Chloroplasts also have DNA in them, but animals do not have chloroplasts.
