DNA replication yog ib txheej txheem kev saib xyuas ib nrab, vim tias thaum tsim cov DNA molecule ob zaug tshiab: Ib txoj hlua yuav yog los ntawm cov qauv qauv qub.
Puas yog DNA replication conservative Semiconservative los yog dispersive?
DNA replication siv semi-conservative method uas ua rau muaj ob txoj kab DNA uas muaj ib leej niam leej txiv thiab ib tug ntxhais tshiab.
Puas yog DNA replication kiag li kev saib xyuas?
DNA replication is a semi-conservative process. Ib nrab ntawm niam txiv DNA molecule raug khaws cia hauv txhua tus ntawm ob tus ntxhais DNA molecules.
Puas DNA rov ua dua kev saib xyuas thiab tsis txuas ntxiv?
DNA replication is semi-conservative thiab semi-discontinuous. Meselson thiab Stahl, 1958 los ntawm kev siv l4N thiab l5N tau lees paub tias qhov rov ua dua ntawm DNA hauv E-coli yog ib qho kev saib xyuas.
Puas yog DNA replication ib txwm Semiconservative?
Cov ntsiab lus tseem ceeb: DNA replication is semiconservative. Txhua strand nyob rau hauv ob chav helix ua raws li ib tug qauv rau synthesis ntawm ib tug tshiab, ntxiv strand. DNA tshiab yog tsim los ntawm enzymes hu ua DNA polymerases, uas yuav tsum tau ib tug template thiab ib tug primer (pib) thiab synthesize DNA nyob rau hauv lub 5' mus rau 3' kev taw qhia.
