What are some key differences between horizintal gene transfer gene transfer and vertical descent with mutation?
horizontal gene transfer refers to a transfer of DNA to another cell that is not its offspring. Vertical occurs when 2 organisms have sex with their penis and produce offspring, it receives genetic material from ancestors (parents)
How does a pathogen enter a new reservoir?
A pathogen can enter a new reservoir through various routes, such as direct contact with infected animals or consumption of contaminated food or water. Once in the new reservoir, the pathogen may adapt to the new host species and establish infection cycles within that population.
Is a protist a pathogen?
Yes they can. Famous ones are Plasmodium the agent of Malaria or trypanosoma species the agents of sleeping illness or chagsa disease
Can fungi be pathogenic?
no
What describes a plasmid?
A piece of DNA transferred by a bacteriumIt is a piece of non-reproductive DNA, typically within a bacterium, that can be transferred to other organisms of the same or different species.
What is a promiscuous plasmids?
A promiscuous plasmid is a type of DNA molecule that can be transferred between different bacterial cells through processes such as conjugation, transformation, or transduction. These plasmids often carry genes that promote their own transfer and can spread rapidly among bacterial populations.
How does lateral gene transfer occur between individuals of a species?
Lateral gene transfer in a species happens when genetic material is exchanged between individuals through processes like conjugation, transformation, or transduction. This allows for the transfer of genes that can lead to genetic diversity within a population.
What is hormonema dematioides?
a plant pathogen, causing reed needles of species af Abies
What is the function of the Ti plasmid?
The Ti plasmid is a circular DNA molecule found in Agrobacterium species. It serves as a vector for transferring genes into plant cells, leading to the formation of crown gall tumors. The transferred genes help the bacterium infect and genetically modify the plant cells to its advantage.
We are putting a gene from one species into another what are we actually transferring?
You would be actually transferring a set of codes expressed as codons that will form the gene. You would be cutting one gene from a chromosome and inserting it in to another chromosome. This is called lateral gene transfer. You would use an intermediate such as a plasmid or virus to complete this transfer. Vertical gene transfer is another name for the genes that a parent passes to their offspring.
What are some key differences between horizintal gene transfer gene transfer and vertical descent with mutation?
horizontal gene transfer refers to a transfer of DNA to another cell that is not its offspring. Vertical occurs when 2 organisms have sex with their penis and produce offspring, it receives genetic material from ancestors (parents)
What does Macrophage do after it ingests a pathogen?
Upon engulfment of a pathogen macrophages will destroy the pathogen in the phagolysosome. This is accomplished through a variety of enzymes as well as the use of reactive oxygen species (free radicals), which are used to produce bleach. Macrophages can then break down the proteins of the pathogen and present them as antigens to T cells, although dendritic cells are much better at this last part.
Can rabbits get worms from cats?
No, rabbits cannot get worms from cats. Each species has its own specific types of parasites that do not typically transfer between them.
How does a pathogen enter a new reservoir?
A pathogen can enter a new reservoir through various routes, such as direct contact with infected animals or consumption of contaminated food or water. Once in the new reservoir, the pathogen may adapt to the new host species and establish infection cycles within that population.
Can a dog get lice from a human?
No, dogs cannot get lice from humans. Lice are species-specific parasites, meaning they are adapted to live on a specific type of host and cannot easily transfer between different species.
Can dogs get lice from cats?
No, dogs cannot get lice from cats. Lice are species-specific parasites, meaning they are adapted to live on a specific type of host and cannot easily transfer between different species.
Can pets carry lice and transmit them to humans?
Yes, pets can carry lice, but they typically do not transmit them to humans. Lice species are usually specific to certain host animals and do not easily transfer between species.
