strand. RNA polymerase binds the proximal promoter region aided by the transcription factor proteins bound on the core part of the promoter. To synthesize RNA in the 5′ to 3′ direction going from left to right, RNA polymerase reads the bottom strand of DNA in the 3′ to 5′ direction....
MLV is an encapsulated positive strand RNA virus with a genome about 8000 nucleotides, including three structural genes (gag, pol and env), encoding viral capsid proteins [matrix (MA), capsid (CA) and nucleocapsid (NC)], protease [reverse transcriptase (RT), integrase (IN) and protease ...
An interesting question is why DNA evolved if RNA existed. The most likely answer is that having a double-stranded molecule helps protect the genetic code from damage. If one strand is broken, the other strand can serve as a template for repair.Proteinssurrounding DNA also confer additional pro...
Human LINE-1 ORF2p relies on upstream single-stranded target DNA to position the adjacent duplex in the endonuclease active site for nicking of the longer DNA strand, with a single nick generating a staggered DNA break. Akanksha Thawani
What are the basic building blocks of DNA and RNA? How was the three dimensional structure of transfer RNA determined? What is E6/E7 viral messenger RNA? What RNA virus replicates in the nucleus? What way is RNA used other than making protein? Does this use involve double-strand RNA or ...
DNA–RNA hybrids and single-stranded RNA (ssRNA) as well as double-stranded DNA (dsDNA) and ssDNA. In addition, Mazina et al.59have characterised an additional function of RAD52 in inverse strand exchange between dsDNA and ssRNA. This process allows the formation of a DNA–RNA hybrid via ...
对于基因组的拼接的概念,我们可以如此描述,从测序中所获取的短DNA序列片段出发,拼接出一个完整的基因组序列的过程就称之为基因组的拼接。在基因组拼接的问题刚刚萌芽之期,人们常常将其模型化处理,使其成为一个最短字符超串问题。而最短字符超串问题,其实质就是设定一个字符串集合为S,在集合S中找出一个最为短捷...

“Penicillimonavirus,”and“Plasmopamonavirus.”Multipartite (−)ssRNA viruses have also been reported from edible shiitake mushroom (Lentinula edodes negative-strand RNA virus 2) andEntoleucasp. infecting avocado (Entoleuca bunyavirus 1). Both viruses have a smaller segment with the putative ...
As shown in Figure 1B, in the next step the mRNA (blue zigzag) must exchange with the 23 nucleotide “sense” strand (blue line) of the short dsRNA. During strand exchange, the 23 nucleotide sense strand dissociates from the enzyme and is replaced by the mRNA. The mRNA is positioned ...
