Chromosome

              A hminga lehkha thiam tawh dek dek chuan chromosome hi kan hre theuhvin a rinawm, Mahse enge a nih chiah, enge a hnathawh, enge a tangkaina, khawilaiah nge a awm, tih erawh hre lo an awm nual thungin a rinawm. "DNA test" tih te pawh hi hre lo tura ka ngaihte pawh hian an hre zel mai. Enge DNA tih te, khawiah nge a awm a, enge a hnathawh tihte erawh an hre chuang lem hlei lo va. Hetiang thil ho mai mai zotawnga ziak hi a har ru zek a nia aw.

              Kum 1875 kum khan a hmasa ber atan chromosome chungchang hi Strasberger chuan a lo ziak tawh a. Chromosome hming hrim hrim phuaha hmang hmasa bertu chu Waldeyer (1888) a ni thung. Cell staining (a mizotawng chuan rawnga chiah kan ti mai dawn em ni) an tih laiin chromosome hi fiah kek kawkin a lang thin a, hei vang hian chromosome hming pawh hi an puttir ta a ni. Chroma = colour, soma = body).

Chromosome lan chian lai:

               Cell cycle hi hun hnih ah then a ni a, Mitotic phase (Division lai) leh Interphase (chawlh lawk lai) te an ni. Interphase hunlai hian chromosome te hi an sin em em mai a, hmuh a harsa em em thin. Mitotic phase hunlai hian chiang takin a lang thin a, mitotic phase hunlai rau rauvah metaphase hunlai hian hmuh a nuam bik thin.

Chromosome hruihrual:

               Lazai sinte hi uluk takin en ila, a aia sin lehzual pahnih in vingvial a ni tih i hmu thei ang. He lazai sin tak invet tlat hi DNA nen ka tehkhin thin a. He lazai sin tak sei em em mai hi hrual ila, chu kan hrualsa chu hrual chhawng chho zel ila, lazai sin sei tak chu tawite lian tak a lo ni ang. Hetiang chiah hian DNA thread sei tak chu a inhrual muk chho chhawng zel a, a tawpah chuan tawite, lian tha tak a lo ni ta a. Chu chu chromosome an ti ta a ni. Chromosome chu DNA hrui sei takin a siam anih chu.

Chromosome structure lar deuh te:

                     Chromosome ah hian a part pawimawh zual thenkhat a awm a, chungte chu chromatids, centromere leh telomeres an ti. Metaphase hunlaiin chromosome te hi ban pali neiin a awm a, chung a ban pali te chu chromatids an ti a, heng a ban pali te hi hmun khatah, a laiah, an inzawm khawm a, an inzawm khawmna lai chu centromere an ti. Chromosome ban pali te hi chromosome dang nen an awmdunin, a chang chuan an inzawm thei thin a, mahse chromosome hmawr tak erawh hi chu tlemin a danglam deuhva, helaiah tak hi chuan a inzawm tak tak thei thin lo. He chromosome hrawr hi telomere an ti.

Mizotawng chuan ziak a har kher mai. Remchang hmasa berah kan chhunzawm ang.
