front 1 southern blotting | back 1 synthesizes DNA |
front 2 northern blotting | back 2 synthesizes RNA |
front 3 western blotting | back 3 synthesizes protiens |
front 4 1st step PCR | back 4 Primers target a specific region |
front 5 2nd step PCR | back 5 Denature DNA (~95°C) |
front 6 3rd step PCR | back 6 Anneal primers (~55°-65°C) |
front 7 1st step cDNA synthesis | back 7 RNA purification |
front 8 2nd step cDNA synthesis | back 8 RNA incubated with reverse transcriptase |
front 9 3rd step of cDNA synthesis | back 9 oligo-dT primer anneals polyA tail of mRNA so reverse transcriptase synthesizes single strands DNA |
front 10 4th step of cDNA synthesis | back 10 mRNA is removed and DNA polymerse copies the cDNA strand |
front 11 5th step of cDNA synthesis | back 11 nick hairpin |
front 12 4th step PCR | back 12 Elongate new DNA strands, using Taq or other DNA polymerase(~72°C) |
front 13 5th step PCR | back 13 Repeat denaturation, annealing, and elongation for 20-40 cycles. |
front 14 miRNA and siRNA similarities | back 14 21-22 nucleotides undergo post-transcriptional processing. participate in RNA interference (RNAi), targeted, RNA- |
front 15 siRNAs | back 15 no data |
front 16 miRNA | back 16 Many are produced by RNA pol II regulate other genes may have a mismatch with target transcripts are implicated in developmental processes may block translation and/or trigger RNA degradation |
