The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.
1. Contraction of the iliacus and psoas major produces flexion of the hip joint
2. quadriceps femoris muscle group
3. A combination of gluteal and thigh muscles also adduct, abduct, and rotate the thigh and lower leg. The tensor fascia latae is a thick, squarish muscle in the superior aspect of the lateral thigh. It acts as a synergist of the gluteus medius and iliopsoas in flexing and abducting the thigh.
4. triceps brachii
5. The major muscle that laterally flexes and rotates the head is the sternocleidomastoid
6. Rectus abdominis
7. The external obliques are the outermost abdominal muscles. They are also key participants in spinal flexion and the compression of the viscera. Individually, they act alongside the internal obliques in lateral flexion and spinal rotation.
8. abdominal external oblique muscle
9. external intercostal muscles
The splitting in of oxygen to form water. At the end of the chain, electrons are transferred to molecular oxygen,which splits in half and takes up H plus to form water.
