Ua kom Deoxyribonucleotides: Lawv yog thawj phos- phorylated thiab hloov mus rau cov ntawv nquaguas muaj peb phosphate residues tsis yog ib qho. Enzymes phosphorylase yog xav tau nrog rau lub zog.
Dab tsi yog ua kom cov nucleotides hauv DNA replication txheej txheem?
DNA polymerase ntxiv ib txoj hlua tshiab ntawm DNA los ntawm kev txuas ntxiv 3′ kawg ntawm cov saw nucleotide uas twb muaj lawm, ntxiv cov nucleotides tshiab sib phim rau qauv strand ib zaug ntawm kev tsim cov phosphodiester bonds.
Yuav ua li cas rau chromosomes thaum DNA replication?
Thaum txhua lub cell faib, ib lub xovtooj yuav tsum luam nws cov chromosomal DNA los ntawm cov txheej txheem hu ua DNA replication. Cov DNA duplicated ces muab faib mus rau hauv ob lub hlwb "ntxhais" uas tau txais cov ntaub ntawv keeb kwm qub qub. Cov txheej txheem no hu ua chromosome segregation.
DNA replication Semidiscontinuous yog dab tsi?
Ib hom DNA replication nyob rau hauv uas ib txoj hlua tshiab yog synthesized tsis tu ncua, thaum lwm qhov yog synthesized discontinuously li Okazaki fragments.
Puas luam tawm siv deoxyribonucleotides?
DNA replication siv ntau tus proteins thiab enzymes (Table 1). … Cov qauv no qhia txog guanosine triphosphate deoxyribonucleotide uas tau muab tso rau hauv DNA strand los ntawm kev tshem tawm ob pawg phosphate kawg los ntawm cov molecule thiab hloov lub zog mus rau cov piam thaj phosphate daim ntawv cog lus.
