1.The________particle halts the translation of the mRNA to a polypeptide before checking to the ER
a. singal recognition, permanently
b. signal recognition protein receptor, permanently
c. singal recognition, temporarily
d. signal recognition protein receptor, temporarily
I think the right answer is "a" but not sure, Please check
It does not permanently halt. Please read:
http://en.wikipedia.org/wiki/Signal_recognition_particle
To determine the correct answer, let's break down the options provided and gather information from the given link.
Option A: "signal recognition, permanently"
Option B: "signal recognition protein receptor, permanently"
Option C: "signal recognition, temporarily"
Option D: "signal recognition protein receptor, temporarily"
The given link is about the signal recognition particle (SRP), which is involved in protein translation. The SRP recognizes a signal sequence on the mRNA and temporarily halts the translation process. It does not permanently stop the translation.
Therefore, the correct answer is Option C: "signal recognition, temporarily."
To confirm this, you can read more about the signal recognition particle and its role in mRNA translation from reliable sources such as textbooks, scientific articles, or educational websites.
