What is the process in which amino acid chain arrange themselves as three-dimensional structures?
a. splicing
b. folding
c. linking
d. splitting

The right answer is B. folding

The translation of the genetic information is done in two stages: one translates the sequence of the bases of the gene into amino acid sequence of the protein is the primary structure; the second translates this sequence into a complex, precisely defined three-dimensional structure, the only one able to confer on the protein its biological activity.

The second stage, or "protein folding", is at present one of the central problems of biological research.

d. the weight of the book

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
