A muscle cramp is a sudden, painful contraction of a muscle, during which movement is difficult. What is happening at the cellul
ar level during a muscle cramp? A. The proteins in the myofibrils become denatured, preventing relaxation. B. A lack of calcium causes the sarcomeres to lock together, preventing relaxation. C. The motor neuron does not send a signal, so the muscle cannot relax. D. Myosin and actin do not fully detach, so the muscle cannot relax.

Active canonical WNT flagging outcomes in enlistment of β-catenin to DNA by TCF/LEF relatives, prompting transcriptional actuation of TCF target qualities.
The extra translation factors have been recommended to enroll β-catenin and tie it to DNA.
The genome-wide example of β-catenin DNA official in murine intestinal epithelium, WNT -responsive colorectal malignant growth (CRC) cells and HEK293 early stage kidney cells.
The two classes of β-catenin restricting locales.
The top notch speaks to most of the DNA-bound β-catenin and co-limits with <em>TCF4, the noticeable TCF/LEF relative in these cells.</em>
