Answer:
All manifestations of mitosis noted so far occur in animal and plant cells, and there are two differences between them. Astral and anastral mitosis: In astral mitosis, the centrioles of the animal cell are involved in the fibers of the aster. Anastral mitosis, on the other hand, is when we don't find both centrioles and asters in plants.
The other difference is Cytokinesis: In animal cells, since there is no cell wall, there is a strangulation of the plasma membrane, and cytokinesis is called centripetal. In plant cells, due to the presence of a cell wall, it is not possible to have a strangulation division. What occurs is an agglomeration in the equatorial region of vesicles originated from the Golgi complex. These vesicles unite, forming a thin strip, separating the daughter cells. After this process, the synthesis of the cell walls extends from the center to the periphery, under the name of the centrifugal division.
Answer:
95 isoadenine bases; adenine bases cannot be determined
Explanation:
In Alien DNA;
- iA complementary with U
- iT complementary with A
- bG complementary with iC
- So if there were 95 nucleotide that contain the uracil then there should also be 95 isoadenine.
- Adenine binds with isothymine in alien DNA and there are no information of isothymine or other bG/iC bases is given, so we cannot determine the adenine bases.
<span>The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipidsand proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and aphosphate-linked head group.
