Cov evolution ntawm kev sib deev muaj ob lub ntsiab lus tseem ceeb sib txawv: nws keeb kwm thiab nws txoj kev tu. Keeb kwm ntawm kev sib deev kev yug me nyuam tuaj yeem taug qab mus rau prokaryotes thaum ntxov, nyob ib ncig ntawm ob billion xyoo dhau los (Gya), thaum cov kab mob pib pauv cov noob ntawm kev sib txuas, hloov pauv, thiab hloov pauv.
Ib yam li ntawd, kev yug me nyuam cuam tshuam li cas rau evolution?
Hauv biology, evolution yog qhov kev hloov pauv ntawm cov khoom qub txeeg qub teg ntawm cov pej xeem los ntawm ib tiam dhau ib tiam. Cov yam ntxwv no yog kev qhia ntawm cov noob uas yog luam thiab xa mus rau cov xeeb ntxwv thaum lub sij hawm kev yug me nyuam . Genetic drift tshwm sim los ntawm lub luag hauj lwm lub caij nyoog plays nyob rau hauv seb ib tug muab ib tug yuav ciaj sia thiab yug me nyuam.
Tsis tas li ntawd, qhov tseem ceeb ntawm kev yug me nyuam yog dab tsi? Kev tsim tawm tiv thaiv txhua yam kab mob los ntawm kev ploj mus. Kev tsim tawm Nws tsis tsim nyog rau kev ua neej nyob ntawm ib tus neeg tab sis pab txhawb cov tib neeg hauv cov pej xeem. Kev tsim tawm Nws yog ib qho tseem ceeb rau kev tsim cov kev hloov pauv hauv cov tsiaj los ntawm geneticrecombination.
Tsis tas li ntawd, dab tsi yog qhov tseem ceeb ntawm kev yug me nyuam hauv evolution?
Lub ntsiab qhov tseem ceeb ntawm kev yug me nyuam yog khaws cia txuas ntxiv ntawm hom. Nws kuj pab tau kev kawm evolution raws li kev sib deev kev yug me nyuam ua rau variation ntawm hom.
Dab tsi yog qhov tseeb evolution?
Hauv biology nws hais txog kev hloov pauv ntawm cov kab mob, mus rau lawv qhovntsej thiaj tsis mob los ntawm ib tug poj koob yawm txwv, thiab ntawm cov txheej txheem thev naus laus zis rau kev hloov pauv ntawm cov noob ntau zaus; Nws tuaj yeem xa mus rau cov kev xav piav qhia (xws li Charles Darwin txoj kev xav ntawm kev xaiv ntuj tsim) uas piav qhia txog cov txheej txheem ntawm evolution.

Yog vim li cas ib tug Dideoxyribonucleotide txiav ib tug zuj zus DNA strand?
Yog vim li cas ib tug dideoxyribonucleotide txiav ib tug zuj zus DNA strand? Txhua strand pib nrog tib primer thiab xaus nrog ib tug dideoxyribonucleotide (ddNTP), hloov nucleotide. Kev koom ua ke ntawm ddNTP txiav tawm qhov loj hlob DNA strand vim nws tsis muaj 3 '-OH pawg, qhov chaw rau kev txuas ntawm cov nucleotide tom ntej
