What are the genotypic differences between F-, F+ and Hfr cells?

Biology
1 answer:
Kitty [74]3 years ago
5 0

Answer:

The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.  

The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.

construct an explanation for the high incidence of tusklessness in the Gorongosa elephant population.
Setler79 [48]

Answer:

Argument: A trend toward an increased incidence of tusklessness will result in decreased population sizes in the

future.

Claim: In the long term, tusklessness in African elephants is not beneficial to populations, even when heavy

poaching is occurring. So, as tusklessness increases, elephant population sizes will decline.

Evidence: Although poachers kill elephants with tusks, elephants rely on their tusks for survival. Elephants use

their tusks to strip bark off trees for food and to dig up water and minerals from the ground. Male elephants

also use their tusks in competitions with other males for females.

Reasoning: Tuskless elephants are probably not as healthy as those with tusks, as they cannot eat bark off trees

and are unable to dig for water and minerals. During harsh conditions such as droughts, elephants without

tusks would be less likely to survive. Male elephants without tusks are also more likely to be injured during

mating competitions. If too many males are injured or killed, there may be a decline in reproduction.

Over time, many of the tuskless elephants will die or be unable to reproduce, so the population’s size will

decrease.

Explain what happened when the isopropanol came in contact with the strawberry extract
castortr0y [4]

The isopropanol will extract the DNA from the strawberries.

Explanation:

Strawberries help in DNA extraction as it has enzymes and pulverizes easily which breaks the cell wall and has large number of DNA in it. The isopropanol helps in precipitating the DNA.

In an experiment of DNA isolation, a squashed and refrigerated strawberry was added in a isopropanol solution after filtering it. It can be seen DNAs are starting to isolate from the strawberry extract in the form of fluffy bubbles.
