Gene을 발현하는 중 ER과 GA에서 생산된 단백질에 당이나 지질을 붙이는 Post Translational Modification과정을 거치지 않는다. 따라서 동물 세포에서 생산되는 단백질과 같이 당단백질이나 당지질 등이 필요하게 되면 생산을 할 수 없다. 따라서 이런 식의 단백질은 많은 한계가 있다. 또한 Yeast는 정도가 크지는

2 .Bidirectional hydrogenase
1) Definition of bidirectional hydrogenase
Unlike uptake hydrogenase, bidirectional hydrogenases are helpful in hydrogen production. The biological role of bidirectional hydrogenase is thought to control ion levels in the organism. Bidirectional hydrogenase is associated with the
by exposure to inescapable stress.
b.BDNF
Neurotrophinsand neurogenesis.
Volumetric decreases observed in the hippocampus and other fore brain regions in subsets of depressed patients have supported a popular hypothesis for depression involving decrements in neurotrophic factors – neurodevelopmentally expressed growth factors that also regulate plasticity within adult brain. From a

Increased intracellular calcium reinforce some cyclic AMP mediated actions of glucagon, particularly on glycogenolysis.

Ketogenesis is the process by which ketone bodies are produced as a result of fatty acid breakdown.

STEP1: ABOUT SKIN CANCER
Cause of cancer _ 2 cases
1.Cell growth doesn’t stop
2.Disorder of apoptosis
p53 : Tumor repressor gene
P53 : transcription factor
Functions
-p53 are that first arrest cell cycle so control cell growth, also active apoptosis suicide program
P53 mutation ->p53 sytem breaks down, it can’t act as Transcriptor factor-> generating tumor
of a psychopath, these people lack the ability to love, and they lack empathy or guilt toward others. If they have shown an understanding or helping behavior toward others, this is merely a deception for another purpose. Also, their ability to endure frustration is very weak. They also strongly and continuously ignore social norms or obligations, and have difficulty in controlling aggression. Fin
