正如宇宙間存在著許多既看不到也感覺不到的“暗物質(zhì)”“暗能

量”一樣,，在生命體這個“小宇宙”中,，也存在這樣的神秘“暗

物質(zhì)”—非編碼RNA。越來越多的證據(jù)表明,，一系列重大疾病的發(fā)

生發(fā)展與非編碼RNA調(diào)控失衡相關(guān),。環(huán)形RNA分子zui近數(shù)年才引起

研究人員注意，而此前的研究主要集中于線形RNA分子,。單革教授

實(shí)驗(yàn)室發(fā)現(xiàn)的新型環(huán)狀非編碼RNA,，被命名為外顯子-內(nèi)含子環(huán)形

RNA。在論文中,，他們還對這類新型環(huán)狀非編碼RNA為何會成為環(huán)

形而不是線形分子進(jìn)行了研究,，發(fā)現(xiàn)成環(huán)序列兩端經(jīng)常會有互補(bǔ)

的重復(fù)序列存在[5]  。細(xì)胞中的分布編輯蟾蜍血涂片（用吡羅紅

甲基綠染色液染色）蟾蜍血涂片（用吡羅紅甲基綠染色液染色）

左圖是用吡羅紅甲基綠染色液染色的蟾蜍血涂片。由于DNA和RNA

在化學(xué)組成與分子結(jié)構(gòu)上存在一定的差別,，因而對不同的染料有

著不同的反應(yīng),。所以，可以根據(jù)這一反應(yīng)差異來研究細(xì)胞中DNA與

RNA的分布情況.RNA主要分布在細(xì)胞質(zhì)中,。DNA和RNA兩種核酸分

子都是多聚體,，但是它們的聚合程度有所不同。DNA聚合程度高,，

易于甲基綠結(jié)合[6]  ,；RNA聚合程度低易于吡羅紅結(jié)合[7]  。

所以當(dāng)吡羅紅與甲基綠混在一起作為染料時(shí)吡羅紅與核仁,、細(xì)胞

質(zhì)中的RNA選擇性結(jié)合,，從而顯示紅色；甲基綠與染色質(zhì)中的DNA

選擇性結(jié)合,，從而顯示綠色,。綜上所述，RNA對吡羅紅的親和力大

,，被染成紅色,；DNA對甲基綠的親和力大，被染成綠色,。組成結(jié)構(gòu)

編輯與DNA不同,，RNA一般為單鏈長分子，不形成雙螺旋結(jié)構(gòu),，但

是很多RNA也需要通過堿基配對原則形成一定的二級結(jié)構(gòu)乃至三級

結(jié)構(gòu)來行使生物學(xué)功能,。RNA的堿基配對規(guī)則基本和DNA相同，不

過除了A-U,、G-C配對外,，G-U也可以配對。在細(xì)胞中,，根據(jù)結(jié)構(gòu)

功能的不同,，RNA主要分三類，即tRNA（轉(zhuǎn)運(yùn)RNA）,，rRNA（核糖

體RNA）,，mRNA（信使RNA）。mRNA是合成蛋白質(zhì)的模板,，內(nèi)容按

照細(xì)胞核中的DNA所轉(zhuǎn)錄,；tRNA是mRNA上堿基序列（即遺傳密碼

子）的識別者和氨基酸的轉(zhuǎn)運(yùn)者；rRNA是組成核糖體的組分,，是

Just as there are many "dark matter" "dark energy" that can neither be seen nor perceived in the universe

In the same vein, in the "small universe" of living bodies, there is such a mysterious "darkness."

Material "- non-coding RNA. More and more evidence that a series of major diseases

Health development is associated with unbalanced regulation of non-coding RNAs. Circular RNA molecules have only been caused in recent years

Researchers note that previous studies have focused mainly on linear RNA molecules. Single leather professor

Labeled new cyclic non-coding RNA, was named exon - intron ring

RNA. In the paper, they also explain why these new circular noncoding RNAs become loops

It has been found that rather than linear molecules, there are often complementary ends of the looping sequence

The repetitive sequence exists [5]. Distribution in Cells Edit toad blood smear (with Pirohyl

Methyl Green stain staining) Toad blood smears (staining with Piroside Methyl Green Stain)

Left panel is a toad blood smear stained with Piroside Methyl Green stain. Due to DNA and RNA

In the chemical composition and molecular structure there are some differences, and therefore have different dyes

Different responses. So, according to this response to differences in the study of DNA and cells

RNA distribution .RNA is mainly distributed in the cytoplasm. DNA and RNA two nucleic acid points

Children are multimers, but their degree of aggregation is different. A high degree of DNA polymerization,

Easy methyl green binding [6]; low degree of RNA polymerization easy to combine with piroxican [7].

So when Pirogyl red and methyl green mixed together as a dye when Pirohyl and nucleolus, cells

The RNA in the plasmid selectively binds to reveal the red; methyl green and DNA in the chromatin

Selective combination to show green. In summary, RNA affinity for piroxicis

, Was dyed red; DNA affinity for methyl green, dyed green. Composition of the structure

Unlike DNA, an RNA is generally a single-stranded long molecule that does not form a double-helix structure

Many RNAs also need to form a certain secondary structure and even three levels through the principle of base pairing

Structure to exercise biological function. The base sequence of RNA is basically the same as that of DNA, no

Except A-U, G-C pairing, G-U can also be paired. In cells, depending on the structure

Different functions, RNA is divided into three categories, namely, tRNA (transport RNA), rRNA (ribose

Body RNA), mRNA (messenger RNA). The mRNA is a template for the synthesis of proteins, according to the content

Transcribed according to the DNA in the nucleus; tRNA is the base sequence on the mRNA (ie, the genetic code

Sub) recognizers and amino acid transporter; rRNA is composed of ribosome components

The workplace for protein synthesis.
