To unequivocally confirm antisense transcription in the region of the V (D)J exon and to extend these assays to wild-type mice, we designed a strand-specific RT-PCR assay to distinguish, in a very clean way, between sense and antisense transcripts through the SHM target region just downstream of the J H segments. Sense strand- It is the segment of double stranded DNA. -Runs from 5' to 3'. -has base sequence same as that of mRNA. -also known as coding strand. Antisense strand-aka template strand. -runs from 3' to 5'. - complimentary to sense strand. -in which transcription occurs. Mis-sense strand- occurs due to single nucleotide polymorphism in codons. A few DNA sequences in prokaryotes and eukaryotes, and more in plasmids and viruses, blur the distinction between sense and antisense strands by having overlapping genes. In these cases, some DNA sequences do double duty, encoding one protein when read along one strand, and a second protein when read in the opposite direction along the other Since replication must occur in the 3'--->5' direction, the lagging strand has to replicate the DNA in chunks (Okazaki fragments) as helicase unwinds the DNA. So basically coding v template and sense v antisense have to do with transcription, while leading v lagging has to do with replication. thanks for clarifying, makes a lot more sense now! :) Each siRNA is unwound into two single-stranded RNAs (ssRNAs), the passenger (sense) strand and the guide (antisense) strand. The passenger strand is then cleaved by the protein Argonaute 2 (Ago2). The passenger strand is degraded and the guide strand is incorporated into the RNA-induced silencing complex (RISC). The RISC assembly then binds and Antisense oligonucleotides targeting regions of the HBV genome have efficiently reduced serum HBsAg and HBV DNA in preclinical studies, both alone and in combination with standard nucleoside therapy. 7 Bepirovirsen (GSK3228836), previously ISIS 505358 or IONIS‐HBV Rx, is a 2′‐O‐methoxyethyl (2′‐MOE)‐modified antisense .
