Somatic cancer cells often are unstable and divide inappropriately (divide when they should not be dividing). In addition such c
ells often contain losses of some chromosomes and extra copies of other chromosomes. Defects in which of the following may be partially responsible for the aberrant behavior of cancer cells? (Select all that apply.) A)spindle-assembly checkpoint
B)G1/S checkpoint
C)homologous chromosome pairing
D)crossing over
G1/S checkpoint is one of the points in the cell cycle, between growth phase 1 and DNA synthesis phase, where a cell that has been damaged is sensed by DNA repair enzymes and further degraded by apoptosis. In cancer cells, there is mutation in these DNA repair enzymes and thus nothing to correct the cells from dividing even when damaged and thus there is no arrest of division and cells continue dividing
Explanation: The main property of the waves is the way how they propagate or travel in medium The waves which can travel without a medium is said to travel in vacuum or air.
The bionic pancreas is a technology created to reduce and adjust blood sugar levels in patients with diabetes. This external device was developed by Ed Damiano's lab at Boston University. This management system is well known to maintain homeostasis by managing blood sugar levels: the bionic pancreas contains two pumps, one with insulin and the second one with glucagon for controlling the sugar levels when they change in the blood.
