All Cells …

Question

All cells …
A) have membrane transport proteins.
B) synthesize proteins on the ribosome.
C) replicate their genome by DNA polymerization.
D) transcribe their genetic information by RNA polymerization.
E) All of the above.

Accepted Answer

All living cells replicate their DNA by the same overall mechanism of templated polymerization. They also transcribe the genetic information into RNA form using the same mechanism. Translation of this information into protein form is mediated by the ribosome in all cells. Additionally, all cellular membranes have membrane transport proteins that control the flow of material through the membranes.
