Ṭhenkhat chuan, "Ka mit hi ka nu mit ang chiah a ni," an ti a, "Ka thinrimna hi ka pa aṭanga lo chhuak a ni," an ti bawk. Heng zawng zawng hi genes, kan taksaa thil te ber berte hian a ruat vek a ni. A awlsam zawngin, heng genes te hi lehkhabu lian tak ang mai a ni a, chutah chuan kan taksa siam dan tur leh a hnathawh dan tur thupek a awm a.

Hei hi vawiina kan sawi tum chu a ni.

A awlsam zawngin, genetic mutation chu eng nge ni?

Genetic mutation chu i taksaa DNA sequence inthlak danglamna a ni. I taksa hi building lian tak angin ngaihtuah rawh. Chu building sakna tur blueprint, a nih loh leh ruahmanna chu i DNA a ni. He DNA ah hian genes a awm a. He ruahmanna hi i taksa chhunga cell tinte tih tur hrilhtu a ni.

Chuti a nih chuan, he blueprint-ah hian khawi emaw laiah inthlak danglamna tlem a awm a, hmun dik lovah line siam a nih chuan, a then chu delete a nih chuan eng nge thleng ang? Chu chu genetic mutation chu a ni. DNA sequence hmun thenkhat chu hmun dik lovah a awm emaw, a kim lo emaw, eng emaw ti taka a chhiat chuan genetic condition symptoms i nei thei a ni.

Engtin nge heng genetic mutations te hi a lo awm a, engtikah nge a lo awm?

Hengte hi cell inthen darh lai hian a thleng tlangpui . Chu chu kan taksaa cell pakhat chauh a inthen a, cell thar a lo pian hian a ni. Lehkhabu lian tak i copy a, lehkhabu tam tak i siam leh ang tih han ngaihtuah teh. I copy lai hian tihsual a awm thei a ni lawm ni? Hetah pawh hi chutiang chu a ni.

Kan taksaah hian he cell inthen darhna hi kawng hrang hrang pahnih a awm a, chungte chu:

1. Mitosis: Hei hi kan taksain cell thar a siam hian a thleng thin. Entîr nân, i vunah hliam i neih chuan, chu chu tidam tûrin cell thar siam chhuah a ngai a ni. Hei hi he inthenna hi hman a ni. Heta thil thleng chu cell awmsa chhunga chromosome awmte copy siam a nih hnuah cell pahnih ah a inthen a ni.

2. Meiosis: Hei hi thil tih dan bik a ni. Egg cell leh sperm cell a siam chhuak a, chu chu thlah thar siamna atana mamawh a ni. Heta thil danglam bik chu original cell-a chromosome 46 awm zinga a chanve chauh, chu chu 23 chauh chu cell tharah an kal a ni. Chuvangin i nu leh pa te hnen atangin genetic information inang chiah chiah i dawng thin.

Chuvangin, he cell inthen darh lai hian DNA copy a nih hian tihsual tenau te a awm thei a ni. Lehkhabu copy lai ang bawkin lehkha pakhat chu dah bo a ni thei a, lehkha pakhat chu sawn a ni thei a, lehkha thar a awm thei bawk.

• Lehkha dang dah belh.

Hetiang tihsual (genetic mutation) a lo awm hian, chu instruction bu-a thupek chu cell-te chuan an chhiar thei tawh lo. A tulna hmun a bo emaw, a tul lo a dah belh emaw pawh a ni thei. Heng zawng zawng hian a tawpah chuan cell te hian an hna an thawk tha thei tawh lo tihna a ni.

Engtin nge genetic mutation hian kan taksa a nghawng?

Genetic mutation chu i cell-te mamawh information tihdanglamna a ni. Kan genes te hi kan taksaa protein siam dan tur instruction a ni. Heng protein te hian kan taksa chhunga thil awm zawng zawng deuhthaw chu an thunun vek a - kan hmel lan dan atanga kan san zawng, vun rawng, leh sam rawng te, taksa chhunga thil thleng zawng zawng thlengin.

Chuvangin gene mutation a awm chuan heng protein siam dan hi a danglam thei a ni. Tichuan cell te chuan hna an thawh tur ni lovin thil danglam tak an ti tan ta a ni. Chuvang chuan genetic diseases symptoms a lo lang thin.

Heng symptoms te hi eng gene ah nge mutation a awm tih a innghat a, mutations avanga natna leh dinhmun hrang hrang a awm a. I natna lan chhuah dan thenkhat chu hetiang hi a ni:

• Taksa pianphung inthlak danglamna: thil chi hrang hrang, hmai dik lo, cleft palate, webbed fingers, leh short stature te.
• Intellectual functioning problems: zirlai lama harsatna leh hmasawnna lama harsatna.
• Mit emaw hriatna lama harsatna nei.
• Thâwk harsa.
• Cancer vei theihna a sang chho.

Genetic mutations zawng zawng hi a chhe vek em? A tha an awm em?

Ni lo, hei hi ngaihdan dik lo awm fo a ni. Gene mutation zawng zawng hian natna a thlen vek lo. Gene mutation thenkhat chu i hriselna tichhe lovin a awm mai mai a ni. A chhan chu DNA sequence-ah inthlak danglamna awm mah se, cell hnathawh danah danglamna lian tham a awm lo.

Chu aia mak zawk chu genetic mutations thenkhat hian kan chungah nghawng tha tak a nei thei tak zet a ni.

Genetic mutations a awm em?

Awle. Heng mutations te hi an awmna hmun a zirin chi hnih ah then theih a ni.

Heng genetic mutations te hi nu leh pa atanga fate hnena pek chhuah a ni em? (Inrochunna)

Ni e, kan sawi tawh ang khan germline mutations hi nu leh pa atanga fate rochun theih a ni. Somatic mutations hi random takin a thleng a, chhungkaw history engmah a awm lo.

Genetic Disorders hi eng nge ni?

Genetic disease chu i genetic material (genome) inthlak danglamna avanga lo awm a ni. Hei hian i DNA, genes leh chromosomes te a huam a ni. Hei hi thil engemaw zat avanga lo awm thei a ni:

• Gene pakhata inthlak danglamna (monogenic) .
• Gene engemaw zat a mutation (multifactorial inheritance) 1.1.
• Chromosome pakhat emaw a aia tam emaw a mutation awm
• Environment factors (chemicals, UV rays nena inzawmna) .

Genetic mutations ven nan hian kan tih theih tur a awm em?

Dik tak chuan, genetic mutations thenkhat hi random-a thleng thin a nih avangin venna tur kan tih theih a awm lo. Mahse, mutations thenkhat chu kan nunphung leh kan chhehvel hian a nghawng a ni. Chumi awmzia chu mutations thenkhat awm theihna tur tihtlem nan hma kan la thei tihna a ni.
