Yog hais tias kev sib koom ua ke ntawm cov chromosome uas tawg lawm xaus nrog ob chromosomes, ob qho kev txawv txav chromosomes tshwm sim: txhua tus muaj ib feem tau los ntawm lwm cov chromosome thiab tsis muaj ib feem ntawm nws tus kheej. Cov no yog hu ua translocations.
Qhov kev hloov pauv twg tshwm sim ntawm ob chromosome?
A translocation tshwm sim thaum ib daim ntawm ib chromosome tawg tawm thiab txuas mus rau lwm chromosome. Hom kev hloov pauv no tau piav qhia tias muaj kev sib npaug yog tias tsis muaj cov khoom siv caj ces tau txais lossis ploj hauv lub cell. Yog tias muaj qhov nce lossis poob ntawm cov khoom siv caj ces, qhov kev hloov pauv tau piav qhia tias tsis sib npaug.
hom kev hloov pauv twg muaj ob lub chromosomes uas tsis yog homologous?
Kev hloov pauv. Translocation muaj ob homologous chromosomes thiab tshwm sim qhov twg ib daim ntawm chromosome tawg tawm thiab rov txuas mus rau lwm cov chromosome uas tsis yog homologous.
ob qhov kev hloov pauv yog dab tsi?
Muaj ntau hom kev hloov pauv. Ob pawg loj ntawm kev hloov pauv yog germline mutations thiab somatic mutations Germline mutations tshwm sim hauv gametes. Cov kev hloov pauv no tseem ceeb tshwj xeeb vim tias lawv tuaj yeem xa mus rau cov xeeb ntxwv thiab txhua lub cell ntawm cov xeeb ntxwv yuav muaj qhov hloov pauv.
Kev hloov pauv puas tuaj yeem yog qhov hloov pauv hloov pauv?
Qee cov kws tshawb fawb pom lwm hom kev hloov pauv, hu ua frameshift mutation, ua ib hom kev hloov pauv. Frameshift mutations tuaj yeem ua rau poob siab heevthiab tshwm sim los ntawm kev ntxiv lossis tshem tawm ntawm ib lossis ntau dua DNA hauv paus.

Dab tsi yog qhov kev hloov pauv hloov pauv?
Nyob rau hauv molecular biology thiab noob caj noob ces, transcriptional regulation yog cov txhais tau tias los ntawm lub cell tswj kev hloov ntawm DNA rau RNA, yog li orchestrating noob kev ua si. Tus tswj hwm kev hloov pauv ua dab tsi?
Puas hloov pauv hloov pauv tuaj yeem hloov kho?
Nyob hauv ntau qhov kev sim, qhov sib txawv ntawm kev ywj pheej yog kev tsim kho uas tsuas yog tuaj yeem tswj tsis ncaj . Puas yog qhov sib txawv nyob ntawm qhov ntsuas lossis tswj tau? Ib qhov sib txawv yog qhov ntsuas lossis manipulated hauv kev sim.
Thaum twg qhov kev hloov pauv hloov pauv tau tsim nyog?
Thaum twg Stepwise Regression tsim nyog? Stepwise regression yog ib qho kev ntsuam xyuas tsim nyog thaum koj muaj ntau qhov sib txawv thiab koj txaus siab txheeb xyuas qhov muaj txiaj ntsig ntawm cov kwv yeesHauv Minitab, tus txheej txheem kev hloov pauv theem ob ntxiv thiab tshem tawm cov kwv yees ib ntawm ib qho.
Qhov twg yog qhov hloov pauv hloov pauv mus rau ntawm daim duab?
Thaum peb npaj cov ntaub ntawv ntawm ib daim duab qhov kev hloov pauv hloov pauv yog ib txwm npaj rau ntawm X - axisthiab qhov sib txawv teb yog ib txwm npaj rau ntawm Y - axis. Independent variable yog lwm lub npe rau kev hloov pauv hloov pauv.
Qhov txawv ntawm kev hloov pauv thiab hloov pauv yog dab tsi?
Raws li verbs qhov txawv ntawm kev hloov pauv thiab hloov yog tias hloov pauv yog siv rau qhov chaw ntawm lwm yam, nrog tib txoj haujlwm thaum hloov yog rov qab mus rau qhov qub, txoj haujlwm, condition, or the like . Qhov txawv ntawm kev hloov pauv thiab hloov pauv hauv Excel yog dab tsi?
