Euchromatin yog thaj tsam ntawm caj ces ntawm chromosome . Nws muaj cov txheej txheem genes uas tau rov ua dua thaum G1 thiab S theem ntawm interphase los ntawm kev tso cai rau polymerases nkag mus rau cov noob. 1.

koj txhais li cas los ntawm lo lus euchromatin?

Euchromatin yog ib daim ntawv me me ntawm chromatin(DNA, RNA, thiab protein) uas yog enriched nyob rau hauv cov noob, thiab feem ntau (tab sis tsis tas li) nyob rau hauv active transcription. Euchromatin suav nrog feem ntau ntawm cov genome hauv lub cell nucleus.

koj txhais li cas los ntawm heterochromatin thiab euchromatin?

Heterochromatin txhais tau tias yog thaj tsam ntawm chromosome uas yog tsaus nti nrog DNA tshwj xeeb stain thiab yog nyob rau hauv daim ntawv sib piv. Euchromatin txhais tau tias yog thaj tsam ntawm cov chromosome uas yog nplua nuj nyob rau hauv gene concentration thiab nquag koom rau hauv cov txheej txheem transcription.

Vim li cas nws thiaj hu ua euchromatin?

Euchromatin Function

Raws li tau hais los saum toj no, euchromatin tseem hu ua beads-on-a-string vim tias qhov zoo ib yam ntawm lub caj dab ntawm cov hlaws dai txuas los ntawm txoj hlua thiab cov nucleosomes txuas nrog. tus linker DNA.

Kev ua haujlwm ntawm euchromatin thiab heterochromatin yog dab tsi?

Heterochromatin tswj cov txheej txheem kev ncaj ncees ntawm cov genome thiab tso cai rau kev tswj hwm ntawm cov noob qhia. Euchromatin tso cai rau cov noob tau sau tseg thiab hloov pauv mus rau hauv cov noob.
