Answer:
B
Explanation:
DNA sequencing is used to determine the order of nucleotides in a DNA sequence, not to separate them
I am sure the answer is due to random sampling of organisms
Answer:
Elongated shape
Explanation:
Centrifugation separates molecules on the basis of angular motion.
Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.
Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.
Hence its elongated shape results in slow centrifugation.
Some of the important principles of centrifugation are as follows :
- The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
- Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
- Density of particles
- Density of fluid
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.
