what is the difference between horizontal gene transfer and vertical gene transfer?
240858
In vertical gene transfer, the transfer of genetic material is from parents to offspring. It may be through sexual or asexual reproduction. In contrast, the horizontal gene transfer is the movement of genetic material from a donor organism to a recipient organism that is not its offspring.

The basic difference between biological transmission and mechanical transmission is that in biological transmission, the agent develops and/or propagates within the vector, while in mechanical transmission, the simple transfer of agents from one infected host or a contaminated substrate to a susceptible host occurs.

Genetic resistance that is effective at preventing successful attack only by certain races of a pathogen is called specific (or vertical) resistance, whereas resistance that is effective at preventing successful attack by all races of a pathogen is called general (or horizontal) resistance.

PCR Is More Time-consuming, But The Purity Of The Obtained DNA Clone Is Much Higher Than In Traditional Cloning. B. PCR Uses Plasmid Vectors, Whereas Traditional Cloning Uses Bacteria.

Gene transfer is a new treatment modality that introduces new genes into a cancerous cell or the surrounding tissue to cause cell death or slow the growth of the cancer. This treatment technique is very flexible, and a wide range of genes and vectors are being used in clinical trials with successful outcomes.

In transformation, the recipient bacterium takes up extracellular donor DNA. In transduction, donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation, the donor bacterium transfers DNA to the recipient by mating.

In general, cloning vectors are plasmids that are used primarily to propagate DNA. ... An expression vector is a specialized type of cloning vector. Expression vectors are designed to allow transcription of the cloned gene and translation into protein.

The primary difference between a biological and a mechanical vector is that: biological vectors play a role in the pathogen's life cycle, whereas a mechanical vector spreads disease without being integral to a pathogen's life cycle.

Although there are exceptions, most bacteria have a single circular chromosome. ... The most important differences between DNA in chromosomes and plasmids lie in where the genetic material is replicated and how mobile it is. Genes on a plasmid can be transferred between bacteria much more easily than chromosomal DNA.

There are two fundamental differences between the methods. One is that molecular cloning involves replication of the DNA within a living cell, while PCR replicates DNA in the test tube, free of living cells. ... Formation of recombinant DNA requires a cloning vector, a DNA molecule that replicates within a living cell.

transduction (prokaryotes) Transduction is the process by which a virus transfers genetic material from one bacterium to another. Viruses called bacteriophages are able to infect bacterial cells and use them as hosts to make more viruses.

New traits can also come from transfer of genes between populations, as in migration, or between species, in horizontal gene transfer. Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.

Whereas molecular genetics is concerned with the study of your favorite gene, genomics is concerned with studying all the genes. This is not to be confused with the distinction between forward and reverse genetics, although reverse genetic approaches invariably follow from genome projects.

Conjugation is the transfer of circular DNA called plasmids through cell to cell contact. Transformation is the uptake of 'free' DNA from the environment. Transduction is the transfer of DNA by bacteria-specific viruses called bacteriophage.

Another key difference is that in the lytic cycle the viruses replicate constantly which results in the eventual lysis, or death, of the host cell to release the new viruses while in the lysogenic cycle the virus replicates only with the regular cellar mechanism for reproduction and is only released through some ...

The distinction between the two is based on purpose. Gene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. Genetic engineering aims to modify the genes to enhance the capabilities of the organism beyond what is normal.

A vertical market is one in which all of your customers are in one particular industry, regardless of where in the food chain they are. ... A horizontal market is one in which all of your customers use your product to do the same thing, regardless of what industry they are in.
