"Host cell translates the viral gene" is the one among the following choices given in the question that <span>happens when a cell transcribes a viral gene. The correct option among all the options that are given in the question is the third option or the last option. I hope that this is the answer that has come to your help.</span>
Answer: It will affect muscle contraction because it is needed for the formation of muscle contraction cross-bridge.
Explanation: During muscle contraction calcium binds to troponin, a protein complex that regulates muscle contraction by exposing the binding site of actin filament. Actin filament active site is where myosin head binds to, creating a cross-bridge using enzyme ATPase to speed the reaction. Calcium ion are needed to activate troponin movement, otherwise it stays in its inactive form blocking the active site of actin filament. Without calcium ions, troponin will not move and there will be no muscle contractions.
