Kuj nug, qhov txawv ntawm ib chromosome ib cov noob ib allele thiab cov protein yog dab tsi?
DNA qhia lub cell yuav ua li cas cov proteins . DNA yog teem rau chromosomes hauv ntu hu ua noob . Ib noob qhia lub cell yuav ua li cas ua ib tug protein ntau . txawv kev hloov pauv ntawm a noob hu ua alleles.
Puas yog tus cwj pwm thiab alleles tib yam?
Cov yam ntxwv yeej yog koj phenotype. Lawv suav nrog tej yam xws li plaub hau xim, qhov siab, thiab qhov muag xim. Alleles yog versions ntawm noob. Lawv yog dab tsi ncaj qha qhia dab tsi yam ntxwv koj muaj.
