Replication, Transcription, thiab Translation yog peb lub ntsiab Cov txheej txheem siv los ntawm txhua lub hlwb los tswj lawv cov ntaub ntawv caj ces thiab hloov cov ntaub ntawv caj ces encodedin DNA rau hauv cov khoom lag luam, uas yog RNAs lossis cov proteins, nyob ntawm cov noob.

Hauv qhov no, peb feem ntawm lub hauv paus dogma ntawm biology yog dab tsi?

Cov central dogma ntawm molecular biology piav qhia txog cov txheej txheem ob kauj ruam, kev sau thiab txhais lus, uas cov ntaub ntawv hauv cov noob ntws mus rau hauv cov protein: DNA → RNA → protein. Kev hloov pauv yog qhov kev sib txuas ntawm RNA daim ntawv theej ntawm cov DNA.

Tsis tas li ntawd, qhov kev txiav txim ntawm lub hauv paus dogma yog dab tsi? Ib lub noob uas encodes ib polypeptide yog qhia nyob rau hauv ob kauj ruam. Hauv cov txheej txheem no, cov ntaub ntawv ntws los ntawm DNA → RNA → protein, ib qho kev taw qhia kev sib raug zoo hu ua thecentral dogma ntawm molecular biology. Transcription: Ib txoj hlua ntawm cov noob DNA tau theej rau hauv RNA.

Ntawm no, Central Dogma txhais li cas?

Kho mob Txhais ntawm centraldogma : ib txoj kev tshawb xav nyob rau hauv noob caj noob ces thiab molecular biology kawm txog ntau yam kev zam uas cov ntaub ntawv noob caj noob ces yog coded inself-replicating DNA thiab undergoes unidirectional hloov tomessenger RNAs nyob rau hauv transcription uas ua raws li templates rau proteinsynthesis nyob rau hauv kev txhais lus.

Peb kauj ruam ntawm kev qhia gene yog dab tsi?

Cov txheej txheem ntawm gene qhia koom nrog ob lub ntsiab theem : Transcription: zus tau tej cov tub txib RNA( mRNA ) los ntawm enzyme RNA polymerase, thiab kev ua haujlwm ntawm qhov tshwm sim mRNA molecule.

Kev txhais lus

  • Kev pib.
  • Elongation.
  • Kev txiav txim.
  • Tom qab kev txhais lus ntawm cov protein.
