Upon centrifugation, particles sediment at different rates due to their physical properties. Tropomyosin is a rod-shaped protein
polet [3.4K]

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

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized to produce F2. If the capital lette
Galina-37 [17]

Answer:

a) How many genotypes will occur in F2

--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)

Reason-

This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.

b) 25% of all F2 genotypes would be recessive across the 5 loci

Reason-

This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.

c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE

d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE
