Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Life Sciences Fundamental Processes Protein synthesis and processing
During heat shock, mammalian cells shut down global protein synthesis while inducing heat shock proteins. The possible molecular regulations that could explain the phenomenon are:
A. mRNA of all proteins except those of HSPs undergo degradation during heat shock
B. Cap-dependent translation of most mRNAs is affected during heat shock due to denaturation of the cap-binding protein eIF-4e.
C. Translation initiation of HSP mRNAs takes place through their internal ribosome entry size IRES
D. HSP mRNAs are abundant during heat shock, and thus they compete with other mRNAs for ribosome binding and translation.
