relation to protein production and packaging in a eukaryotic cell, which step occurs first?
A. The ER membrane pinches off to encircle the protein.
B. In the nucleus DNA instructions are copied as RNA messages.
C. Proteins cross the membrane of the rough ER and enter the ER.
D. The vesicle holding the protein travels through the endoplasmic reticulum and out into the cytoplasm.

The answer would be b. in the nucleus DNA instructions are copied as RNA messages. This is called translation. The RNA then takes that information to the ribosome where it is transcribed into amino acids, which will form a polypeptide chain and create a protein

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
