(a) What is RNA polymerase? (b) What is its function? What is responsible for the replication of mRNA? What are the role of DNA polymerase and RNA polymerase? What is polymerase chain reaction (PCR) and what impact does it have in DNA and RNA?
In fission yeast, factors involved in the RNA interference (RNAi) pathway including Argonaute, Dicer, and RNA-dependent RNA polymerase are required for heterochromatin assembly at centromeric repeats and the silent mating-type region. Previously, we have shown that RNA-induced initiation of transcriptio...
RNases are a broad class of enzymes that are specific for cleaving RNA molecules. RNases are commonly used in molecular biology laboratories during the purification of DNA and proteins. Different sub-classes of RNase are present, such as RNase A, RNase H, RNase P, RNase L, RNase III, ...
RNA polymerase is poised for activation across the genome - Muse, Gilchrist, et al. - 2007 () Citation Context ... of H3K4me3 in S regions might derive from high occupancy RNAP II p-ser5. ChIP has been used to determine RNAP II association at specific promoters and transcribed regions ...
Production of messenger RNA in eukaryotic cells is a complex, multistep process. mRNA polyadenylation, or 3' processing, requires several protein factors, including cleavage/polyadenylation-specificity factor (CPSF), cleavage-stimulation factor, two cleavage factors and poly(A) polymerase. These proteins...
In transcription, RNA polymerase How is DNA replication different from DNA transcription? In transcription, only a single DNA strand is used as a template to create a complementary strand of mRNA. In transcription, one of the two DNA strands is copied...
10.in which process,transcription or translation,do each of the following function:RNA polymerase,ribosomes,nucleotides,tRNA,pre-mRNA,DNA A site,anticodon,amino acids? 相关知识点: 试题来源: 解析 最上面的算是第二问吧?2、如楼上所说,一是因为DNA不能通过核孔,二是DNA为双螺旋结构,转录成RNA翻译更...

DNA-DNA 杂交检测中,在杂交前需要增加靶 DNA 的变性步骤(对 mRNA的原位杂交无需此步)。样品 DNA 的变性可能会造成样品形态学的部分破坏,此步是实验中需要优化的一个步骤。实验时可以摸索变性时间、变性温度等参数以获得条件。可以将探针的变性和样品 DNA 变性同步进行:将样品和探针溶液加盖盖玻片,置于烘箱 80℃变...
Male germ cell development requires precise regulation of gene activity in a cell-type and stage-specific manner, with perturbations in gene expression during spermatogenesis associated with infertility. Here, we use steady-state, nascent and single-cell RNA sequencing strategies to comprehensively charact...
