Erosion can de-form/ruin landforms, & for sediment, it can erupt the rock cycle.
Hope this helped! :D
Answer:
d
Explanation:
i think I haven't studied this in a while but I'm confident in that answer
Answer:
The correct option is option C, nucleus
Explanation:
As the scenario described in the question, the medicine X functions on the DNA as it's characteristic shows that it is damaging the DNA. The DNA is present inside the nucleus of a cell. Hence, for a medicine to function on the DNA, the medicine must enter the nucleus of the cell as it is the location where the DNA is present.
Other options like, option D, is not correct because the process of conversion of mRNA into proteins takes place in the ribosomes and DNA is not present there.
Answer:
The steps can be the following:
1. Free DNA fragments from the donor cell bind to the recipient cell.
2. A DNA strand is digested by the bacterial nuclease and the excess strand is absorbed.
3. The coated DNA and the DNA of the recipient cell are brought together to achieve a homologous sequence.
4. DNA base pair alignment occurs through DNA ligase.
5. The integration of the exogenous DNA resulting from the recombination is completed, completing the transformation.
Explanation:
Transformation can be said to be the genetic variation of a cell that results from the uptake, incorporation and expression of exogenous DNA from its environment, which is absorbed by the cell membrane. The recipient bacteria have to be in a state of competition, and this type of competition can be induced in a laboratory, so that the bacterial cell is permeable to DNA when exposed to certain conditions. For this, the cells are incubated in a solution that has various divalent cations, such as calcium chloride, before exposing them to thermal shock. The main function of calcium chloride is to alter the cell membrane, allowing the recombinant DNA to enter the host cell. These types of cells can be called as competent cells.
