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.

of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding e
tia_tia [17]

Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment while on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

What are the three mechanisms by which transcription factors regulate eukaryotic gene expression
sergiy2304 [10]

<span>1.       </span>They act as activators of transcription. This is through increasing the affinity of the RNA polymerase on the promoter

<span>2.       </span>They could act as repressors. This way, when they bind to their active sites, they repress the binding of the RNA polymerase on the promoter

<span>3.       </span> Transcription factors at one site could affect transcription of genes on another site on the DNA. The flexibility of the DNA (by forming loops) allows for this phenomenon.
