Chaperone proteins or chaperones assist in the proper folding of proteins. Explain the process.
oksian1 [2.3K]

Proteostasis is mediated by chaperone proteins and protease systems, together with cellular clearance mechanisms such as autophagy and lysosomal degradation.

Chaperone proteins control assembly and inaccurate folding by binding to and stabilizing partly or completely unfolded protein polypeptides till the polypeptide chain is completely synthesized. Chaperone proteins also confirm the stability of unfolded polypeptide chains as they are being translocated into the subcellular organelles.

77julia77 [94]

Answer;

-Birth rate

Explanation;

-The birth rate is the total number of live births per 1,000 in a population in a year or period. For example; in one year, 35 giraffes are born to a population.

-A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.
