A researcher exposes a bacterial culture to UV radiation and then subjects it to progressively higher temperatures. As the tempe
rature increases, the bacteria have a progressively harder time surviving. Analysis of the dead bacteria reveals large amounts of misfolded, aggregated proteins compared to wild-type control bacteria exposed to the same temperature increase. Which of the following is a plausible explanation for the data? A. The ribosomes are mutated and are non-functional.
B. The initiator tRNA (fMet) has been mutated and is non-functional.
C. Molecular chaperones have been mutated.
D. DNA polymerase is mutated and non-functional.
In prokaryotes; transcription and translation occur consecutively. Protein doubling additionally happens following the translation. The heat stun proteins or molecular chaperones are imperative to assume a part in the appropriate collapsing of the protein. At high-ranging temperatures, the protein misfolding can be ascribed to a change in mutation of the molecular chaperones.
It contains a carbon atom that bonds to six other atoms instead of the four we have been told carbon is limited to. Atoms form molecules by sharing electrons. Carbon has four electrons that it can share with other atoms
Cell membranes are found in both bacteria and archaea, and they both feature a hydrophobic part. Both bacteria and archaea have a protective cell wall.
