A noob yog ib ntu luv ntawm DNA. Koj cov noob muaj cov lus qhia uas qhia koj cell ua ua molecules hu ua proteins. Proteins ua ntau yam haujlwm hauv koj lub cev khaws cia koj noj qab nyob zoo. Txhua noob nqa cov lus qhia uas txiav txim siab koj nta, xws li qhov muag xim, xim plaub hau thiab qhov siab.
Tsis tas li ntawd, koj cov caj ces hais li cas txog koj?
Koj Genes Thiab Koj Nws hu ua DNA, thiab feem ntau yog tib yam rau txhua tus. Tab sis ib feem me me ntawm nws yog koj ib leeg. Cov kev sib txawv no pab txiav txim seb yuav ua li cas koj saib, txoj kev koj lub cev ua haujlwm, koj pheej hmoo rau kab mob, thiab koj tus kheej.
Tsis tas li ntawd, cov noob puas txiav txim siab peb txoj hmoo? Whew! Koj DNA tsis yog Koj Destiny . Qhov ntau peb kawm txog tib neeg genome, qhov tsawg DNA zoo li txoj hmoo . Raws li cov kws tshawb fawb tshawb pom ntau ntxiv txog "epigenome," ib txheej ntawm biochemical tshuaj uas tig mus noob nyob rau hauv thiab tawm, lawv tau pom tias nws plays ib qho tseem ceeb hauv kev noj qab haus huv thiab heredity.
Ib yam li ntawd, muaj cov noob zoo txhais li cas?
Cov noob zoo kev xav. biology. Cov noob zoo hypothesis, nyob rau hauv biology, ib qho kev piav qhia uas qhia tau hais tias qhov zoo ntawm cov poj niam xaiv thaum xaiv ib tug txiv neej yog cov qhia ncaj ncees ntawm tus txiv neej lub peev xwm mus dhau. noob uas yuav ua rau kom muaj sia nyob lossis kev loj hlob ntawm nws cov xeeb ntxwv.
Cov noob kis tau li cas?
Chromosomes yog dhau los ntawm niam txiv mus rau cov xeeb ntxwv ntawm cov phev thiab qe. Yam tshwj xeeb ntawm chromosome uas muaj a noob txiav txim siab li cas noob yog qub txeeg qub teg. Yog li ntawd, txhua tus neeg muaj ob daim ntawv theej (alleles) ntawm txhua tus noob nqa ntawm autosome: ib tug tau txais los ntawm lawv txiv thiab ib tug los ntawm lawv niam.
Pom zoo:
Dab tsi yog txhais los ntawm cov noob tseem ceeb thiab cov noob caj noob ces?
(Nyob rau hauv cov ntsiab lus ntawm caj ces, ib qho tseem ceeb tshaj plaws yog ib qho uas yog phenotypically qhia hauv heterozygotes). Ib qho tseem ceeb tshaj plaws yog tawm tsam qhov tsis zoo uas tshwm sim tsuas yog thaum muaj ob daim ntawv theej ntawm cov noob. (Nyob rau hauv cov ntsiab lus genetic, ib tug recessive zoo yog ib tug uas yog phenotypically qhia tsuas yog nyob rau hauv homozygotes)
Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Yuav ua li cas tus tsim cov nyhuv ua rau cov noob caj noob ces?
Genetic drift tuaj yeem ua rau poob loj ntawm kev hloov caj ces rau cov neeg me. Qhov tshwm sim tus tsim tshwm sim thaum lub colony tshiab pib los ntawm ob peb tus tswv cuab ntawm thawj cov pej xeem. Cov pej xeem me me no txhais tau hais tias cov cheeb tsam yuav muaj: txo cov noob caj noob ces los ntawm cov neeg qub
Koj cov noob caj noob ces hais li cas txog koj?
Koj Genes Thiab Koj Nws hu ua DNA, thiab feem ntau yog tib yam rau txhua tus. Tab sis ib feem me me ntawm nws yog koj ib leeg. Cov kev sib txawv no pab txiav txim seb koj zoo li cas, koj lub cev ua haujlwm, koj txoj kev pheej hmoo rau kab mob, thiab koj tus cwj pwm
Vim li cas kev nkag siab txog noob caj noob ces tseem ceeb rau cov tub ntxhais kawm?
Vim li cas kev kawm noob caj noob ces tseem ceeb? Nyob rau yav tom ntej, cov kws kho mob thiab cov kws tshawb fawb vam tias yuav siv peb cov ntaub ntawv caj ces los kuaj, kho, tiv thaiv thiab kho ntau yam mob. Cov noob yog cov lus qhia, uas qhia koj lub cev yuav ua li cas ua kom tag nrho cov proteins nws xav tau kom muaj sia nyob thiab loj hlob
