Genes yog cov units ntawm heredity thiab yog cov lus qhia uas ua rau lub cev daim ntawv qhia. Lawv code rau cov proteins uas txiav txim siab zoo tag nrho ntawm ib tug neeg tus yam ntxwv. Feem ntau cov noob tuaj ua khub thiab ua los ntawm cov khoom siv caj ces hu ua deoxyribonucleic acid, lossis DNA.
Yog li ntawd, dab tsi yog lub hauv paus unit ntawm heredity?
Ib tug gene yog tus yooj yim lub cev thiab ua haujlwm unit ntawm heredity . Cov noob yog tsim los ntawm DNA. Qee cov noob ua raws li cov lus qhia ua cov molecules hu ua cov proteins.
Kuj Paub, yog vim li cas cov noob hu ua lub tsev ntawm heredity? Cov noob yog hu ua raws li cov keeb kwm koj yog vim lawv nqa caj ces cov ntaub ntawv qhia cov niam txiv rau cov menyuam yaus / tawm qhov chaw tawm. Cov kab mob tshwm sim : Cov noob muaj nyob rau hauv chromosomes ntawm DNA. Cov noob nqa cov cim los ntawm niam txiv mus rau cov xeeb ntxwv uas yog lub luag haujlwm rau kev hloov pauv ntawm keeb kwm tus cwj pwm.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub hauv paus chav tsev ntawm heredity nyob qhov twg?
Cov yooj yim ua haujlwm unit ntawm heredity hu ua noob. Lawv kuj yog cov qauv unit ntawm heredity . Lawv yog nyob ntawm chromosomes thiab lawv qhov chaw hu ua loci (singular-locus). Cov noob tuaj yeem yog cov kab ke ntawm DNA hauv qee cov kab mob thiab cov RNA hauv qee qhov lwm tus.
Dab tsi yog qhov zoo tshaj plaws txhais ntawm heredity?
caj ces . Keeb kwm yog cov txheej txheem lom neeg lub luag haujlwm rau kev dhau ntawm lub cev zoo ntawm ib tiam mus rau lwm tus. Keeb kwm yuav txiav txim siab ib tug neeg cov plaub hau xim thiab qhov siab. Thiab vim caj ces , qee tus neeg muaj kev pheej hmoo ntau dua rau cov kab mob thiab kab mob xws li mob qog noj ntshav, haus dej cawv, thiab kev nyuaj siab.
