Yog lawv txuas ncaj qha mus rau sab ntawm lub taub hau, lawv yog txuas earlobes . Qee cov kws tshawb fawb tau tshaj tawm tias qhov zoo li no yog vim muaj tib lub noob uas tsis sib txuas pob ntseg yog dominant thiab txuas earlobes yog recessive. Qhov loj thiab cov tsos ntawm lobes kuj yog tau qub txeeg qub teg yam ntxwv.
Tsis tas li lo lus nug yog, yuav ua li cas txuas pob ntseg txuas?
Autosomal Cov yam ntxwv xav txog earlobe txuas . Ib tug tib autosomal noob nrog ob alleles txiav txim seb koj puas tau txuas pob ntseg los yog free-hanging pob ntseg . Allele rau free-hanging pob ntseg (F) yog dominant rau allele rau txuas pob ntseg (f).
Ib yam li ntawd, vim li cas qee cov neeg earlobes txuas? " txuas "zoo li pob ntseg feem ntau nthuav tawm ua piv txwv ntawm ib qho yooj yim "ib noob - ob alleles" Mendelian qhov zoo ntawm tib neeg, pob ntseg tsis txhob poob zoo nyob rau hauv ob pawg; muaj ib tug tas mus li ntau yam ntawm ib tug huab mus rau lwm yam, tawm tswv yim lub hwj chim ntawm ob peb noob.
Ib yam li ntawd, nws yog nug, muaj pes tsawg tus earlobes txuas?
Dawb Pob ntseg : Dawb pob ntseg yog feem ntau feem ntau daim ntawv ntawm lobes pom. Yog niam txiv nrog dawb pob ntseg yug me nyuam nrog txuas earlobes , Nws yog qhov tseeb tias ob leeg ntawm lawv muaj ob qho tib si luam tawm ntawm cov tseem ceeb thiab recessive allele. Txuas Earlobes : Cov hom no pob ntseg tsis tshua muaj, tab sis kuj tsis tshua pom.
Ob niam txiv nrog pob ntseg puas tuaj yeem muaj tus menyuam tsis muaj pob ntseg?
Qee zaum ib tus neeg muaj qhov tseem ceeb muaj ib tug zais recessive allele. Yog tias lawv dhau qhov ntawd (thiab lwm yam niam txiv ua too), then the menyuam yuav muaj tus yam ntxwv recessive. Yog li ob niam txiv nrog pob ntseg yuav tsum tsis tau muaj ib tug me nyuam nrog tsis sib haum cov.

Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Lub luag haujlwm ntawm cov protein txuas txuas yog dab tsi?
Lub luag haujlwm ntawm cov protein txuas txuas yog dab tsi? Lawv txuas cov strand DNA polymerase thiab cov lagging strand DNA polymerase ua ke
Vim li cas cov lus pom tsis zoo siv hauv RC txuas txuas ntxiv?
Nyob rau hauv ib qho RC txuas ntxiv amplifier, txawm hais tias nws muab peb lub zog zoo dua, qhov nce tam sim no, bandwidth, kev ntseeg siab, peb yuav tsum txo qis lossis ua kom qhov nce siab tshaj plaws kom ua tiav cov txheej txheem peb xav tau kev tawm tswv yim. Cov lus teb tsis zoo: cov lus qhia tawm tswv yim raug rho tawm los ntawm qhov chaw cim
Puas yog earlobes txuas nrog?
Txuas pob ntseg: Cov lus dab neeg tsis muaj pob ntseg feem ntau yog siv los qhia txog cov noob caj noob ces. Cov lus dab neeg yog tias pob ntseg tuaj yeem muab faib ua ob pawg meej, pub dawb thiab txuas nrog, thiab tias ib tus noob tswj tau qhov zoo, nrog rau cov allele rau pob ntseg dawb yog qhov tseem ceeb. Tsis yog ib feem ntawm cov lus dab neeg tsis muaj tseeb
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
