Which statement below describes a feature that is shared between kinesin and dynein? a. Both proteins "walk" towards the (+) end
spin [16.1K]

Answer:

C)Both proteins bind ATP and F-actin

*C option is not mentioned* there is a flaw in the question

Explanation:

Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While

both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.

Alekssandra [29.7K]

Answer:

a. It is a dihybrid cross

b. 0%

c. 0%

d. 0%

e. 100%

f. 0%

g. 0%

Note: Answers are given assuming that hhRD = hhDD

Explanation:

a. The cross, HHdd x hhDD is a dihybrid cross involving two traits: fruit colour and fruit shape

2. Gametes produced in the cross are given below:

for HHdd= Hd and Hd

For hhDD = hD and hD

Offspring produced in the cross:

All HhDd, which represents white and the flattened disc-shaped fruit white since They are both dominant characters.

b. Percentage of the offspring from this cross expected to have the HHDD genotype = 0%

c. Percentage of the offspring from this cros expected to have the hhDD genotype = 0%

d. Percentage of the offspring from this cross expected to have the HhDd genotype = 0%

e. Percentage of the offspring from this cross are expected to produce white and disc-shaped fruits (HHDD or HhDD or HhDd) = 100%

f. Percentage of the offspring from this cross expected to produce white and spherical fruits (HHdd or Hhdd) = 0%

g. Percentage of the offspring from this cross expected to produce yellow and disc-shape (hhDD or hhDd) = 0%
