Macromolecules in the mammals are of three different types, namely the carbohydrates, proteins, and the nucleic acids. Among these macromolecules, the nucleic acids are capable of self-replication. These encode the genetic information of the organism, and plays a vital role in carrying out an array of different functions of the body. One example of such nucleic acid is the RNA, or the Ribonucleic Acid.

Answer: rough endoplasmic reticulum--b
Smooth endoplasmic reticulum--a,c,d
Explanation:The rough endoplasmic reticulum has numerous ribosomes attached to it. Thus it has a coarse texture.it is involved in the production of proteins. The ribosomes receives the messages to produce a protein from the messenger RNA, the ribosome the packs amino acid into proteins and transfers it to the rough endoplasmic reticulum.
The smooth endoplasmic reticulum does not have ribosomes attached.it is involved in the production of non-protein molecules eg lipids and fats.
It is an also important organelle for the metabolism of the cell.it helps in detoxification in the liver. It also stores calcium for use in the skeleton.The sarcoplasmic reticulum is an modified smooth endoplasmic reticulum
