Answer:
phytoflaggellates, e.g. Euglena, and photosynthetic bacteria.
Explanation:
Its is called the control group
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.
Answer:
That's the creation mandate: that we should be fruitful and multiply, that we should fill, subdue, and rule the earth.
