Lub tshuab ntawm kev hloov pauv muaj qhov sib npaug ntawm DNA rov ua dua. … Tsis zoo li DNA replication, nyob rau hauv uas ob strands yog theej, tsuas yog ib strand yog transcribed. Cov strand uas muaj cov noob yog hu ua qhov kev nkag siab strand, thaum lub strand complementary yog antisense strand.
Vim li cas ob txoj hlua DNA tsis tau theej thaum lub sijhawm luam tawm?
Ob RNA molecules, yog tias tsim tawm ib txhij yuav ua tiav rau ib leeg, li no yuav tsim ob txoj hlua RNA.
Yuav ua li cas yog tias ob lub DNA strands raug theej hauv kev sau ntawv?
Yog tias muaj cov neeg txhawb nqa kev tshaj tawm ntawm ob kab ntawm koj tus qauv, ces koj yuav tau txais RNA los ntawm ob qho tib si. Feem ntau, thaum sau los ntawm plasmids thiab linear PCR cov khoom lag luam, tsuas yog yuav muaj ib qho kev txhawb nqa ntawm ib lub xaib.
Tus txheej txheem twg yog ob qho tib si DNA strands tau sau tseg?
Short / Long Answer Type: Tsim kom tiav transcription chav tsev nrog promotor thiab terminator raws li tus qauv hypothetical strand muab hauv qab no sau RNA strand transcribed los ntawm cov ntaub ntawv sau los saum toj no nrog rau nws cov polarity.
Puas luam theej DNA?
Kev txhais lus yog txheej txheem uas cov ntaub ntawv hauv strand ntawm DNA tau theej rautus qauv tshiab ntawm tus xa xov RNA (mRNA). … Txawm hais tias mRNA muaj cov ntaub ntawv tib yam, nws tsis yog ib daim qauv ntawm tib yamDNA ntu, vim nws cov kab ke sib txuas ntxiv rau DNA qauv.
