<p><strong>Lecture 3 - Genomics</strong></p>

<p>* What is <u>Genomics</u>?<br />
&nbsp; &nbsp;► We should remember two things.<br />
&nbsp; &nbsp; &nbsp; &nbsp;- &#39;T&#39; = 7 billion persons (species diversity) + 7 billion bases (variability in one person)<br />

&nbsp;&nbsp;&nbsp;► Every life or species have genome, and variation of each genome is different.</p>

<p>&nbsp;</p>

<p>* GEP/T graph.<br />
&nbsp;&nbsp;&nbsp;► Geno + Enviro -&gt; Pheno/Trait (almost cases are disease)<br />

&nbsp;&nbsp; &nbsp; &nbsp;- Prediction is conducted by experiment, bioinformatics, etc.<br />
<br />
&nbsp;&nbsp;&nbsp;►&nbsp;The challenge : As life is so complicated, prediction is so hard. We have to consider environmetal complexity with genomic complexity.<br />
&nbsp;&nbsp; &nbsp; &nbsp;- Possible solution : using AI based on big data.<br />
<br />
&nbsp;&nbsp;&nbsp;► Solutions<br />
&nbsp;&nbsp; &nbsp; &nbsp; (1) Exact large amount of data.<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;- It is so important.<br />
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; - typing (cheap and efficient) : simple test, approximation (not 100% prediction).<br />
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; - sequencing (ultimate) : almost 100% prediction, digital device, it can have error (we don&#39;t know reason of error), ex) hardware.<br />
&nbsp;&nbsp; &nbsp; &nbsp; (2) Need principle, law, and algorithms.<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;- We need to know related principle when we face to some facts.<br />
&nbsp;&nbsp; &nbsp; &nbsp; (3) Big computer.<br />
&nbsp;&nbsp;&nbsp;</p>

<p>* Genome&nbsp;sequencing.<br />
&nbsp; &nbsp;►&nbsp;2<sup>nd</sup> generation : multiple molecule -&gt;&nbsp;approximation<br />
&nbsp;&nbsp;&nbsp;►&nbsp;3<sup>rd</sup> generation : single molecule<br />
&nbsp;&nbsp;&nbsp;►&nbsp;4<sup>th</sup> generation : nanopore + membrane<br />
<br />
&nbsp;&nbsp;&nbsp;► Base calling : computer notifies types of bases.<br />
&nbsp;&nbsp;&nbsp;► NSG Data analysis : mapping based on reference gene.</p>

<hr />
<p>* Close species comparative genomics.<br />
&nbsp;&nbsp;&nbsp;► If we sequencing genome of new species, we have to find and get right right samples.<br />
&nbsp; &nbsp; &nbsp; &nbsp;- we should pick sample which has interesting phenotype.<br />
&nbsp;&nbsp; &nbsp; &nbsp; - And then, set up experimental design.<br />
<br />
&nbsp; &nbsp;► Gene assembly : assemble gene fragments after putting&nbsp;the known gene between&nbsp;the intereted gene fragments.<br />
&nbsp;&nbsp; &nbsp; &nbsp; - expensive<br />
&nbsp;&nbsp; &nbsp; &nbsp; - After assmbling genome of one species, we can use it as reference genome.<br />
<br />
&nbsp;&nbsp;&nbsp;► MRCA : most recent common ancestor -&gt; we can predict&nbsp;</p>
