Question

Does endoplasmic reticulum contain DNA?

Answer 1

Endoplasmic reticulum does not contain any DNA ,they have the role in synthesizing proteins via the translation process. DNA is found in nucleus and only two cell organelles and they are mitochondria and chloroplasts.

Complete answer:
Endoplasmic reticulum is an organelle found in all Eukaryotic animal and plant cells. They appear as interconnected sub compartments and are divided into two parts namely the rough endoplasmic reticulum and smooth endoplasmic reticulum both the types consist of membrane and closed, interconnected flattened tubes. The rough endoplasmic reticulum contains ribosomes Which help in protein synthesizing and dispatch of these proteins.
Endoplasmic reticulum is associated with Leopard or fat manufacturing and metabolism and also the steroid production has a role in detoxification. The Endoplasmic Reticulum membrane is continuous with nuclear envelope and the Golgi apparatus of part of Golgi body is also associated with endoplasmic reticulum. endoplasmic reticulum and Golgi apparatus work together to package chemical product synthesized into vesicles and transported them to the cytoplasm .the cells DNA is found in nuclear only or in only two cell organelles that are mitochondria and chloroplast because they are semi autonomous organelle, because their role found in energy synthesizing functions.

Note:
Endoplasmic reticulum do not contain any DNA they have only role in synthesizing protein via the translation process and and in Lipid production and detoxification of chemicals as they do not have any circular chromosome, As far as DNA is always found on chromosomes and mainly comprise gene which code for proteins.
