Why is potassium able to diffuse easily in and out of cells? because potassium has a greater concentration in the intracellular
umka2103 [35]

The answer is Because the resting plasma membrane is more permeable to potassium

Plasma membrane is more permeable to potassium(kalium) than sodium(natrium)  which makes it easier to move between intracellular fluid and extracellular fluid. But the concentration of the ion still regulated strictly by the cell using pump and transporter in their membrane. The pump is doing active movement(against gradient of concentration) and need ATP to do so.

If one strand of DNA has the base sequence TTCCGGAA The complementary strand has which of the following sequence?
Mazyrski [523]

Answer:

If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.

Explanation:

A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other .

The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.

  • <em>Adenine is combined with Thymine A=T </em>
  • <em>Cytosine is complemented with Guanina C≡G </em>

In this way, given a sequence on a DNA strand :

<em>     T-T-C-C-G-G-A-A</em>

The complementary strand will have this sequence:

<em>     A-A-G-G-C-C-T-T</em>
