Lecture 1 - What is the bioinformatics?

Lecture 1
What is the bioinformatics?
-> Mapping biological phenomena such as molecular biology, biochemistry.. by using tools(for example : programming)

There are many contents in some area(ex : bioinformatics). But it is no time to know all of things. What is the best strategy for the area?
1. select the part which you want
2. learn about basic and general principle. study detail of the area later.

What is the life?
-> Life is a switch

What is the component of life?
-> Time, Energy, Information

<Controversy>  
AI (artificial intelligence) is life? - it has electrical energy and information and can think what to do in the future
Virus is life? - it has genetic information and process evolution as time pass and can earn chemical energy from host cell.

Hierarchy of life
cell -> tissue -> organ -> organism -> population -> species -> genus -> family -> order -> class -> phylum -> kingdom -> domain -> universe

What is the epigenetics?
-> It is a kind of inheritance that can`t change DNA component(nucleotide) but it can affect the DNA by external methode such as methylation, acetylation
