How do large molecules move across the cell membrane through facilitated diffusion?

Biology
1 answer:
Svetlanka [38]3 years ago
8 0

Answer:

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

The genes dumpy (dp), clot (cl), and apterous (ap) are linked on chromosome II of Drosophila. In a series of two-point mapping c
Dmitrij [34]

Answer:

The order of genes is- dp-cl-ap

Explanation:

The genes a be mapped on chromosome on the basis of the recombination frequency as the recombination shows that is the genes are linked or not.  In genetic mapping, 1 per cent recombination frequency is considered as 1 cM or map distance.

In the given question, the three gene distance are provided on the basis of which the gene can be mapped in the following manner:

1. Take the higher value of gene distance that is 42 m.u and plot them on the line,

2. now place second-highest value on the line that is 39 m.u.

3. The gene will be arranged in the order of dp-cl-ap.

4. dp--³---cl-----------³⁹---------------------ap.

Thus, dp-cl-ap is correct.
