Replicative DNA polymerases cannot initiate DNA synthesis de novo and rely on dedicated RNA polymerases, primases, to generate a short primer. This primer is then extended by the DNA polymerase. In diverse archaeal species, the primase has long been know
Numerals indicate the amino acid positions delimiting the domains and motifs of each protein. The initial adaptation of the native S. pyogenes CRISPR-Cas9 nuclease system into a powerful genome editing tool involved expressing human codon-optimized Cas9 open reading frames (ORFs) and RNA Pol III-...

Table 5.1.Five types of RNA. Type of RNASummary mRNAThe transcript product of a structural gene that encodes an amino acid sequence. tRNATransfer RNA molecules recognize codons of mRNA and facilitate incorporation of each successive amino acid during protein synthesis. ...
The genetic material of viruses may be single- or double-stranded DNA or RNA.Retrovirusescarry their genetic material as single-stranded RNA and produce theenzymereverse transcriptase, which can generate DNA from the RNA strand. Four-stranded DNA complexes known asG-quadruplexes have been observed ...
PrimerSelect能推测引物形成self-dimers,pair-dimersandhairpins的可能性。 单击选定〝Bestchoice〞引物。 从报告菜单〔REPORTMENU〕,选AmplificationSummary,打开左面的窗口。显示用所选个引物做PCR扩增反应的报告。 选择CompositionSummary,打开左面的窗口,描述扩增区和引物对的碱基组成。
1.核酸的质量和纯度对杂交结果有很大影响,因此需要确保提取的DNA和RNA质量良好。 2.杂交反应的条件需要根据具体的实验要求进行优化,以确保杂交的特异性和灵敏度。 3.在进行洗涤步骤时,需要使用低盐溶液进行多次冲洗,以去除未杂交的DNA和RNA以及其他杂质。 4.检测方法的选择需要根据实验要求和样本特点进行选择,以确保...
Genomics generally refers to studies that use a multitude of new high-throughput methods to study DNA, RNA, and organelle genomes for comparative, functional, and environmental studies. Genomic approaches require the use of bioinformatics, highly sophisticated computerised analyses that help decipher ...
DNA and RNA both carry genetic information, but there are quite a few differences between them. For example, DNA's double-stranded structure provides stability and protection for genetic information, while RNA's single-stranded nature makes it more chemically reactive and prone to being broken down...
