Why does it make biochemical sense that chaperones recognize hydrophobic surface area? What catastrophic event are chaperones me
dexar [7]

Answer:

Molecular chaperons in the cells helps in protein folding. These are the group of proteins that have functional similarity and they also assist protein folding.

They have the ability to prevent the non specific binding and aggregation by the binding of the non native proteins.

Molecular chaperons helps in recognizing the hydrophobic surfaces of the unfolded proteins because they themselves are hydrophobic in nature and will combine to the hydrophic binding and bonding.

This helps in guiding the protein to folding.

The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams
