Rov ua dua yog duplication ntawm ob-strands ntawm DNA . Kev sau ntawv yog tsim ntawm ib leeg, zoo tib yam RNA los ntawm ob-stranded DNA . Ob txoj hlua sib cais thiab tom qab ntawd txhua txoj hlua txuas ntxiv DNA Cov txheej txheem yog recreated los ntawm ib tug enzyme hu ua DNA polymerase.
Hais txog qhov no, qhov txawv ntawm DNA replication thiab transcription yog dab tsi?
Kev sau ntawv luam cov DNA rau RNA, thaum rov ua dua ua lwm daim ntawv DNA . Ob txoj kev koom nrog kev tsim cov molecule tshiab ntawm nucleic acids, ib yam nkaus DNA los yog RNA; Txawm li cas los xij, kev ua haujlwm ntawm txhua tus txheej txheem yog heev txawv , nrog rau ib qho kev koom tes hauv gene qhia thiab lwm tus koom nrog hauv kev faib cell.
Ib yam li ntawd, qhov kev hloov pauv txawv ntawm DNA replication 4 qhov sib txawv li cas? 1. DNA replication yog tus txheej txheem ntawm kev ua ob tug ntxhais strand qhov twg txhua tus ntxhais strand muaj ib nrab ntawm cov thawj DNA ob helix. Kev sau ntawv yog tus txheej txheem ntawm synthesis ntawm RNA siv DNA raws li tus qauv. Ua kom RNA luam ntawm tus kheej cov noob.
Yog li, ob qhov sib txawv ntawm kev sau thiab DNA replication quizlet yog dab tsi?
Cov ntsiab lus hauv cov teeb no (2) Rov ua dua ua DNA , Kev sau ntawv ua RNA los ntawm DNA . Rov ua dua qhov kawg tshwm sim yog ob cov menyuam ntxhais, Kev sau ntawv Qhov kawg tshwm sim yog protein molecule. 4. Rov ua dua xav tau ib tug primer, Kev sau ntawv tsis.
Dab tsi yog qhov txawv ntawm replication transcription thiab translation quizlet?
Kev sau ntawv yog tus txheej txheem uas DNA tau theej rau hauv mRNA. Kev txhais lus yog qhov kev txiav txim siab ntawm mRNA cov lus rau hauv cov protein. DNA yog hauv zoo li ob lub helix. Hauv DNA rov ua dua , DNA molecule untwists, thiab enzymes, hu ua DNA polymerase, phim li dawb-floating nucleotides rau ib qho ntawm thawj DNA strands.

Raws li lub voos xwmfab loj zuj zus los yog lub xov tooj ntawm tes tau loj dua, ces thaj tsam ntawm qhov ntim rau qhov sib piv - SA: V piv txo. Thaum ib yam khoom / cell me me, nws muaj thaj tsam loj rau qhov ntim piv, thaum lub khoom loj / cell muaj thaj tsam me me rau qhov ntim piv
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
