Genes yog ntu ntawm deoxyribonucleic acid (DNA) uas muaj cov cai rau cov protein tshwj xeeb uas ua haujlwm hauv ib lossis ntau hom hlwb hauv lub cev. Chromosomes yog cov qauv hauv cov hlwb uas muaj tib neeg lub cev noob . Genes yog muaj nyob rau hauv chromosomes , qho yog nyob rau hauv lub cell nucleus.

Ua li no, cov noob puas tsim cov hlwb?

Cov noob muaj nyob rau ntawm me me spaghetti zoo li cov qauv hu ua chromosomes (hais: KRO-moh-somes). Thiab chromosomes pom nyob rau hauv hlwb . Koj lub cev yog ua ntawm billions ntawm hlwb . Cells yog cov me me heev uas ua txhua yam muaj sia.

Qhov thib ob, DNA cuam tshuam li cas rau cov noob? DNA (deoxyribonucleic acid) yog lub cell caj ces cov khoom, muaj nyob rau hauv chromosomes nyob rau hauv lub cell nucleus thiab mitochondria. Ib chromosome muaj ntau yam noob . A noob yog ib ntu ntawm DNA uas muab cov cai los tsim cov protein. Cov DNA molecule yog ib tug ntev, coiled ob helix uas zoo li ib tug kauv staircase.

Qhov thib ob, dab tsi yog cov noob caj noob ces?

A noob yog lub hauv paus ntawm lub cev thiab kev ua haujlwm ntawm cov noob caj noob ces. Cov noob yog ua nce ntawm DNA. Ib txhia noob ua raws li cov lus qhia los ua cov molecules hu ua cov proteins. Txawm li cas los xij, ntau noob tsis code rau cov protein.

Puas yog cov noob ua los ntawm DNA?

Cov noob yog ua ntawm ib qho tshuaj hu ua DNA , uas yog luv rau 'deoxyribonucleic acid'. Cov DNA molecule yog ob lub helix: uas yog, ob ntev, nyias strands twisted ib ncig zoo li ib tug kauv staircase. Cov sab yog qab zib thiab phosphate molecules.
