Question
Which ONE of the following statements is NOT a feature of the endoplasmic reticulum (ER)?Question 13Select one:a.It contains folded layers of membraneb.It is the site where transcription of DNA into mRNA occursc.Parts of the ER are connected to ribosomes, the sites of protein synthesisd.The ER is involved in protein distribution for further processing after synthesis
Solution
The statement that is NOT a feature of the endoplasmic reticulum (ER) is:
b. It is the site where transcription of DNA into mRNA occurs
Explanation: Transcription of DNA into mRNA occurs in the nucleus, not the endoplasmic reticulum. The ER is involved in protein synthesis and distribution, and it does contain folded layers of membrane and is connected to ribosomes. However, the process of transcription, which is the first step in gene expression, happens within the nucleus.
