Is there any virus that contains both DNA and RNA in its genome? It is known that viruses contain DNA or RNA- either one and not both. I came across a question: Which virus contains both DNA and RNA?
Here is the results summary of the study that describes the discovery of DNA:RNA hybrid virus: > Results Bioinformatic analysis of viral metagenomic sequences The virus genome appears to be the result of a RNA-DNA recombination event between two ostensibly unrelated virus groups.

Ribosomal RNA amount in a Drosophila cell I am isolation RNA from Drosophila larvae brain with TRIzol method. What percentage of extracted RNA will be ribosomal RNA? I am only interested in mRNA, so I am trying to fig...
Many RNA protocols will separate mRNA by affinity of a carrier to the polyA tail. This protocol references an older paper that estimates that only 5% of RNA is mRNA.

How can a continuous RNA be transcribed in the lac operon? The lac operon has 3 genes: lacZ , lacY and lacA. I have seen that the m-RNA transcript of these genes has stop codons in between. So, how can the RNA be made...
RNA Pol doesn't worry about stop codons. Transcription termination can occur through the formation of a hairpin in the new RNA sequence, or through the action of Rho proteins.

Y RNA
失去了保守的与Ro60蛋白的结合位点的突变人类Y RNA仍然能参与DNA复制，这说明与Ro蛋白结合以及启动DNA复制是Y RNA的两种互不相干的功能。尽管Y RNA的衍生小型RNA大小与微RNA相当，但是它们却和微RNA在功能上却毫无关系。 在该情况下，抗辐射奇异球菌的菌体内至少会出现4种短RNA，其中一种RNA似乎与Y RNA具有同源性。 参考 外部连结 非编码RNA wikipedia.org

Purpose of poly(A)+ RNA? I am learning RNA-seq analysis. I always encounter this phase "poly(A)+ RNA". After searching, I got this: "Most messenger RNAs contain a poly(A) tail, while structural RNAs do not. Poly(A) se...
One of the primary reasons to use poly(A) selection is to eliminate the massive amount of ribosomal RNA (rRNA) present in the samples. The alternative is to use ribosomal RNA depletion kits / techniques to remove as much rRNA as possible before sequencing.

RNase Inhibitors | RNA Protection | RNase Inhibition
RNasin® RNase Inhibitors work by binding strongly to RNases, preventing them from degrading vulnerable RNA molecules during manipulation in the laboratory. Reliable RNase inhibitors satisfy three major criteria: 1) They protect RNA and do not introduce RNAses; 2) They are compatible with experimental conditions used in multiple applications ...

基因、染色体、蛋白质、DNA、RNA 之间的关系是什么？
基因：是遗传的基本单元，是产生一条多肽链或功能RNA所必需的DNA片段。可以简单理解为好长一段DNA链中比较特殊某段。 染色体:细胞内具有遗传性质的遗传物质深度压缩形成的聚合体，易被碱性染料染成深色，所以叫染色体。 那么RNA呢？从汉语名称来看，都应该知道，脱氧之后就变成了DNA。但是，RNA和DNA在组成上的主要差别是：①RNA的糖分子是核糖，DNA的是脱氧核糖，②四种碱基中有一种不同。 zhihu

How do cells determine RNA types? I was reading about the different types of RNA polymerases, and I am confused as to how a cell determines which type of RNA it is transcribing. According to this nature article: > R...
Rather, the gene has the elements, just like it does to select the RNA Pol it needs, to direct the sort of modification the RNA needs to obtain. The image below depicts two types of RNA transcribed by RNA Pol II and how the processing elements let the modification machinery know how to handle them

基因、染色体、蛋白质、DNA、RNA 之间的关系是什么？
蛋白说：“你好，我是RNA水解酶。”mRNA沉默了一下，说：“没关系,反正我本来也活不了多久.你就陪陪我吧。”蛋白说：“好”。于是两个人就手拉手默默地站在一起。过了一会儿蛋白忽然说：“其实我现在还不是RNA水解酶。”mRNA：“嗯。”蛋白：“我现在只是多肽。”mRNA笑了。 蛋白：“可是我很快就会变成真的RNA水解酶了。”mRNA：“没有关系。我总是要死的。”于是蛋白依旧和mRNA靠在一起，他慢慢地转圈，折叠，开始修饰自己。他越来越像真的RNA水解酶，而mRNA慢慢地开始降解。蛋白说：“我走吧，离开了我你也许能活得久一些呢。”mRNA说：“你别走。我有些话要和你说。” zhihu
