Experiments involving in vitro translation of short synthetic RNAs eventually confirmed that the genetic code is indeed a triplet code. The

DNA bender: Cren7 & Sul7 DNA benders can introduce a bend in the DNA (Luijsterburg et al.‚ 2008). Many bends in the DNA automatically provide compaction of the DNA. Two important DNA bending proteins in crenarchaea are Cren7 and Sul7 (Driessen et al.‚ 2013). They are similar in structure‚ but they have different DNA binding regions (Zhang et al.‚ 2015). Cren7 and Sul7 can be methylated at several lysine residues (Guo‚ 2007). This PTM might be to regulate gene expression (Feng et al.‚ 2010)‚ although

Identification and characterization of Pierisin gene in P. napi The strategy was followed to amplify the Pierisin-6 gene was given in the supplementary Fig. 1. The mRNA of pierisin-6 gene was purified from the total RNA of fifth instar larvae of P. napi‚ the conserved region was amplified using gene specific primers (supplementary table-1)‚ cloned into pGEM®-T vector and sequenced. Further‚ 3’ and 5’ untranslated regions of pierisin-6 gene were identified by 3’/5’ RACE-PCR. The amplified cDNA sequence

Genetic engineering is a type of engineering where genes are modified to find cures‚ diseases‚ and more. Genetic engineering uses the central dogma‚ which is the idea of taking. DNA transcribing it into RNA translates it into protein and expressing it as a trait. Recombinant plasmids are when DNA fragments are inserted into a plasmid vector. The recognition site is where the plasmid gets cut by the restriction enzyme which is an enzyme that cuts a DNA molecule. Recombinant DNA is the DNA being inserted

According to the Central dogma of molecular biology‚ "DNA makes RNA makes protein." Translation is the process by which RNA makes protein. In the cell‚ DNA makes messenger RNA (mRNA). mRNA travels to the ribosome which reads its sequence and makes protein coded to that sequence. In molecular biology and genetics‚ translation is the third stage of protein biosynthesis (part of the overall process ofgene expression). In translation‚ messenger RNA (mRNA) produced by transcription is decoded by the ribosome

This means that copies of RNA will not be created and this will limit the amount of certain proteins and enzymes available during critical times in development and growth. http://www.youtube.com/watch?v=erOP76_qLWA&feature=related The dogma of molecular biology entails the transcription of genetic information from DNA onto RNA and the translation

Characterization of LIC13341 and its orthologs. The CDS LIC13341 from L. interrogans Copenhageni genome was cloned without its predicted signal peptide in pET28a expression vector and induced its expression in E. coli BL21. Induction of protein expression was evaluated using 0.5 mM IPTG where recombinant protein (43 kDa) overexpression was remarkably observed (Fig 2A). In order to further characterize LIC13341‚ polyclonal antibodies were generated in BALB/c mice against r-LIC13341. To check its
