Euchromatin koom nrog hauv kev hloov pauv ntawm DNA mus rau mRNA cov khoom. Cov qauv nthuav tawm tso cai rau cov noob tswj hwm cov proteins thiab RNA polymerase complexes los khi rau DNA sib lawv liag, uas tuaj yeem pib ua cov txheej txheem transcription.
Vim li cas euchromatin genetically nquag nquag?
Cov khoom siv caj ces ntawm chromosomes yog chromatin. Cov chromatin yog tsim los ntawm DNA, protein, thiab RNA. … Euchromatin yog thaj chaw genetic active cheeb tsam ntawm chromosome. Nws muaj cov txheej txheem cov noob uas tau hloov pauv thaum lub sijhawm G1 thiab S theem ntawm interphase los ntawm kev tso cai rau polymerases nkag mus rau cov noob.
Cov txiaj ntsig ntawm euchromatin yog dab tsi?
Histone hloov kho ua rau muaj kev tswj hwm ntawm DNA transcription. … Cov noob muaj nyob rau hauv heterochromatin tsis siv tau rau kev sau ntawv. Acetylation txhawb kev tsim ntawm euchromatin (hauv qab) uas tso cai rau kev hloov pauv ntawm cov noob hauv cov cheeb tsam no.
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.
Puas yog euchromatin metabolically nquag siv?
Euchromatin tsis pom tsawg dua li heterochromatin nyob rau hauv lub teeb tsom iav vim nws txoj kev xoob. Euchromatin yog txuam nrog cov hlwb uas yog metabolically active.
