If the base sequence on a separated DNA strand is CGTAGG, what will the base sequence on its complementary strand be?

1 answer:

6 0

To determine what the base sequence for the complementary strand, would be simply remember the base pairing or nitrogenous base pairing rules, for which nitrogen containing base hydrogen bonds or complementary base pairs with another.

A = T
G = C

So the complementary strand would be :
GCATCC.

If an animal cell is placed in plain water, It will swell and burst. The bursting of the cell is a result of which biological pr

densk [106]

Answer:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

Explanation

Cells encounter osmosis due to their semi-permeable membranes. Water can flow past cell membranes. A given cell placed into distilled water will have some water flow into it, causing it to burst. A given cell placed in a very concentrated water will have some water flow out of it, causing it to shrivel. A given cell placed in a solution with the same concentration of minerals as the cell will have an equilibrium of water flowing in and out. This is the case of IV (Intravenous therapy) when we want to deliver substances into a human blood. We want to make sure the liquid delivered is as concentrated as the blood to avoid cell shriveling or bursting.

This picture above sums up the 3 cases cells could face in a solution.

Good luck!
