What type of genetic recombination in bacteria involves DNA transfer by viruses?
There are many ways that genetic recombination could occur in bacteria. One way that it occurs is because of habitat.
What is the advantage of genetic recombination as a mode of reproduction in bacteria?
greater genetic variation. (e2020 answer)
What is recombination?
Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule. In eukaryotes recombination commonly occurs during meiosis as chromosomal crossover between paired chromosomes. This process leads to offspring having different combinations of genes from their parents and can produce new chimeric alleles.Genetic recombination is the process by which two DNA molecules exchange genetic information, resulting in the production of a new combination of alleles. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on to progeny. Most recombination is naturally occurring. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information exchange between the chromosomes. The information exchange may occur without physical exchange (a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed)(see SDSA pathway in Figure); or by the breaking and rejoining of DNAstrands, which forms new molecules of DNA (see DHJ pathway in Figure). Recombination may also occur during mitosis in eukaryotes where it ordinarily involves the two sister chromosomes formed after chromosomal replication. In this case, new combinations of alleles are not produced since the sister chromosomes are usually identical. In meiosis and mitosis, recombination occurs between similar molecules (homologs) of DNA. In meiosis, non-sister homologous chromosomes pair with each other so that recombination characteristically occurs between non-sister homologues. In both meiotic and mitotic cells, recombination between homologous chromosomes is a common mechanism used in DNA repair.Genetic recombination and recombinational DNA repair also occurs in bacteria and archaea.Recombination can be artificially induced in laboratory (in vitro) settings, producing recombinant DNA for purposes including vaccinedevelopment.V(D)J recombination in organisms with an adaptive immune system is a type of site-specific genetic recombination that helps immune cells rapidly diversify to recognize and adapt to new pathogens.
Why are bacteria often used in biological studies?
They are less complex and their genomes are easily manipulated. The plasmids in bacteria provide an oppertunity for simple genetic recombination exercises. Bacteria can be easily made to be lab dependent so that if an accidental release occured there would be no contamination because the bacteria can not live outside the lab environment.
What is the difference between the conjugation that occurs between paramecia and the conjugation that occurs between bacteria?
this Q was awnsered by someone else already and this is what it put and im 90% sure its right- In paaramecia, two individuals of different mating types come together and form a cytoplasmic bridge between them. This is followed by a complex set of divisions and i that ultimately results in an exchange in genetic material between the conjugants analogous to the sexual reproduction seen in multicellular organisms. In bacteria, a structure called the sex pilus "joins" the two organisms and allows for an exchange of genetic information.
What does the paramecia eat?
Paramecia feed on bacteria and algae.
What food do paramecia?
Paramecia feed on bacteria and algae.
Which process performs genetic recombination?
Genetic Recombination is the exchange of genetic information in order to increase the genetic diversity of the population. Probably only with bacteria.
Are paramecia and amebas fungi?
No, they are types of bacteria.
What type of genetic recombination in bacteria involves DNA transfer by viruses?
There are many ways that genetic recombination could occur in bacteria. One way that it occurs is because of habitat.
What does paramecia eat?
They feed of micro-organisms like bacteria, yeasts and algae
What is the advantage of genetic recombination as a mode of reproduction in bacteria?
greater genetic variation. (e2020 answer)
Which is an asexual reproductive cell?
Bacteria.
Can you put two different types of DNA in a single bacteria cell?
Yes; this is referred to as recombination.
How do paramecia get their food?
The cilia on a paramecium create currents in its environment that draw food towards the paramecium. The food is then collected into its oral groove, which will later be put into a cavity, which will later be turned into a vacuole. Paramecia feed on bacteria and algae.
Bacteria employ what reproductive strategy?
Rapid
Why are Paramecia heterotrophic?
Paramecium can not make their own food as autotrophs can so they are " other eaters, " heterotrophs. I think they basically consume bacteria.
