What is the job of the endoplasmic reticulm

So, the endoplasmic reticulum does many things, such as folding the protein molecules in sacs called cisternae. It also transports synthesized proteins in vesicles to the Golgi apparatus.

The correct answer is -  Base pairing rule and DNA.

Explanation:

According to the base pair rule during transcription, along with antisense strand DNA, the RNA was made and the bases of the purines and pyrimidines strands bind together, Uracil paired with the A-strand and the C strand being paired to G-strand in transcription within the nucleus.

Thus, the correct answer in the first line is "Base-pairing rule" while in the second line is "DNA".
