A signal molecule in the interstitial fluid binds to a receptor on the cell membrane, triggering an intracellular cascade. Which

Lady bird [3.3K]

<h2>Function of The Cell Membrane</h2>

Explanation:

There are a few unique kinds of this simple development of particles. It could be as basic as atoms moving uninhibitedly, for example, assimilation or dispersion.
Proteins are utilized to help move atoms all the more rapidly. It is a procedure called encouraged dispersion.
It could be as straightforward as acquiring a glucose particle. Since the cell film won't permit glucose to cross by dispersion.
The cells are in a zone where there is a huge focus contrast. For instance, oxygen particle focuses could be exceptionally high outside of the cell and extremely low inside.
Those oxygen particles are little to such an extent that they can cross the lipid bilayer and enter the cell.
This is a water explicit procedure. For the most part, cells are in a domain where there is one convergence of particles outside and one inside.
Since focuses like to be the equivalent, the cell can siphon particles in an out to remain alive. Assimilation is the development of water over the layer

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?

Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
