Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.
If muscles did not generate opposing forces, then the contraction and relaxation of muscles leading to movement will be limited.
Explanation:
Basically skeletal muscles work in pairs of agonist and antagonist muscles which work together but with opposing forces to contract and relax respectively. These opposing forces help to facilitate movement. Like in a bicep curl, the biceps work as agonist and triceps work as antagonist. The muscular strength is the force that acts against the opposing force of muscles. This strength is regardless of age, sex, weight or size of an individual.
