A nonfunctioning protein will be produced
It’s gases. Gas particles are always moving around. They have no fixed position and so they have high energies. Density depends on how many particles are present, so if the gas particles move around freely there will be very less density, but if you compress them their particles will increase in number thereby increasing the density
Cell division has two checkpoints namely, G1 checkpoint and spindle assembly checkpoint. The checkpoint which determines if division has properly occurred is the G1 checkpoint. At this point, is a damage in the DNA is detected or the has not reach the optimum size, the cell is stopped in G1 and is not allowed to proceed to further process.
