這個問題一點也不笨
不過只要有牽扯到機制說明的話，由於是網路講解，會很容易說不清楚
這個部分專有名詞又爆多
我就大約就campbell 3th提到的部分，就我自己所理解的部分敘述一下
看不懂的地方千萬要再問
首先要先定義operon這個名詞
operon︰生產一個酵素所需要的整段DNA
這一段序列會包含 promoter, operator, structural genes
promoter︰一段 DNA 序列，給 RNA polymerase 結合的地方
operator︰一段 DNA 序列，操控 structural genes 的開關，
掌管RNA polymerase可否通過operator到達structural genes
structural genes：可以解碼出polypeptides的地方
所以說呢，會有如此一個簡圖
regulatory promoter operator structural
gene genes
▊▊▊
↓ ꈠ ↑ ↓ ↓ ↓
mRNA ──── RNA polymerase ꈠ ───────────
↓ ★ ↓
●regulator enzyme
★RNA polymerase結合上會向右進行transcription
●regulator是為 inactive repressor 或是 active repressor
一但 repressor成為 active repressor與 operator結合，把 RNA polymerase擋住
就會抑制 RNA polymerase的 transcription
active repressor = 阻斷transcription
沒transcription = 沒translation = 沒polypeptides = 沒protein = 沒enzyme
接下就要進入正題啦팠以 trp operon跟 lac operon來解釋機制
negative gene regulation其中repressor又分
repressible enzyme 合成的東西會抑制生產 (trp operon)
inducible enzyme 平常關著，靠inducer來激發生產 (lac operon)
positive gene regulation CAP (catabolite activator protein)
trp operon
regulatory gene → inactive repressor
不會阻擋RNA polymerase，於是 RNA polymerase很快樂的 transcription出 mRNA
mRNA也不錯快樂的translation出一堆enzyme
enzyme活化出的產物就是trp啦
structural genes → enzyme ～(活化出) trp
trp + inactive repressor = active repressor
active repressor與operator結合，阻擋RNA polymerase transcription
如此可以稱trp為corepressor
簡單的說 只要體內trp濃度一高，trp operon就會關上，避免浪費
lac operon
regulatory gene → active repressor
平常就阻擋了RNA polymerase
allolactose + active repressor = inactive repressor
於是RNA polymerase就可以執行他的工作啦
如此可以稱allolatose為inducer
structural genes → beta-galactosidase等等
beta-galactosidase使lactose → glucose + galactose
也會有一點allotose
所以只要有lactose持續增加 = allotose增加 = operon打開
簡單的說 只要細胞內lactose增加 = allolatose增加 = lac operon才打開
把lactose消耗掉 = allolatose慢慢變小 = lac operon回復關閉型態
請注意，平常lac的regulatory gene有點漏，所以一但細胞有lactose進來，
就會轉出alloctose，打開operon，但是基本上regulatory gene解碼出repressor
就屬於negative gene regulation
CAP....我要睡了...明天講
明天在上色

接下來是CAP，CAP就可以說是positive gene regulation的例子
CAP (catabolite activator protein)
cyclic AMP (cAMP)
CAP binding site 位於promoter的polymerase binding site的上游 (upstream)
==========================================================================
CAP binding
regulatory site operator structural
gene ↓ promoter genes
▊▊▊
↓ ꈠ ↑ ↓ ↓ ↓
mRNA ──── RNA polymerase ꈠ ───────────
↓ ↓
regulator enzyme
==========================================================================
體內glucose不夠的時候會導致cAMP的累積
cAMP + CAP 就與CAP binding site結合
使得RNA polymerase容易與promoter結合
激發translation
CAP-cAMP複合體在許多operon都有作用
而repressor有專一性
如果在lac operon 為例子的話
在repressor 是inactive 型態為前提
CAP-cAMP複合物會增加transcription
所以是positive gene regulation
對了，上篇跟這篇所提到的lac opero 與trp operon都是原核生物才有喔
