Metacentric chromosomes muaj the centromere nyob nruab nrab ntawm qhov kawg ntawm chromosome, cais ob caj npab ntawm chromosome (Daim duab 1). Chromosomes nrog centromeres positioned pom nyob rau hauv nruab nrab yog hu ua submetacentric.
Metacentric chromosome txhais li cas?
Metacentric chromosome: Ib chromosome nrog caj npab ntawm qhov ntev sib npaug.
Puas metacentric chromosome normal?
Ib chromosome yog metacentric yog tias nws ob txhais caj npab yog qhov sib npaug ntawm qhov ntev. Hauv tib neeg karyotype, tsib chromosomes raug suav hais tias yog metacentric: 1, 3, 16, 19, 20. Qee zaum, ib qho metacentric chromosome yog tsim los ntawm kev sib npaug ntawm kev hloov pauv: fusion ntawm ob lub acrocentric. chromosomes tsim ib tug metacentric chromosome.
Dab tsi yog qhov tshwj xeeb ntawm metacentric chromosome?
Metacentric chromosome muaj a centromere nyob nruab nrab thiab nws ob txhais caj npab (chromatids) yuav luag sib npaug ntawm qhov ntev. B. Metacentric chromosome muaj centromere nyob rau sab thiab nws ob txhais caj npab (chromatids) tsis sib npaug ntawm qhov ntev.
Metacentric hauv biology yog dab tsi?
Ib chromosome uas muaj nws cov centromere nyob nruab nrab. Saib kuj acrocentric chromosome.

Dab tsi yog bivalent chromosome?
Ib tug bivalent yog ib khub ntawm chromosomes hauv tetrad. Lub tetrad yog lub koom haum ntawm ib khub ntawm homologous chromosomes lub cev tuav ua ke los ntawm tsawg kawg ib qho DNA crossover. Qhov kev sib txuas ntawm lub cev no tso cai rau kev sib haum xeeb thiab kev sib cais ntawm homologous chromosomes hauv thawj qhov kev faib meiotic.
Dab tsi yog tus lej chromosome?
Gametes muaj ib nrab ntawm cov chromosomes uas muaj nyob rau hauv ib txwm diploid hlwb ntawm lub cev, uas tseem hu ua somatic hlwb. Haploid gametes yog tsim thaum lub sij hawm meiosis, uas yog ib hom cell faib uas txo cov chromosomes nyob rau hauv niam txiv diploid cell los ntawm ib nrab .
Dab tsi yog qhov txawv ntawm chromatin chromatid thiab chromosome?
Dab tsi yog qhov txawv ntawm chromatin, chromatids, thiab chromosomes? Chromatin yog DNA thiab cov proteins uas tsim los ntawm chromosome. Chromosomes yog cov khoom sib cais ntawm DNA hauv ib lub cell. Thiab Chromatids yog zoo tib yamdaim DNA tuav ua ke los ntawm ib lub centromere .
Leej twg yog metacentric chromosome?
A metacentric chromosome yog a chromosome uas nws centromere nyob hauv nruab nrab Vim li ntawd, chromosomal caj npab (piv txwv li p thiab q caj npab) yuav luag sib npaug ntawm qhov ntev. Ib tug metacentric chromosome yuav muaj X zoo li. Ib chromosome nrog me ntsis sib npaug chromosomal caj npab ntev yog hu ua submetacentric chromosome .
Dab tsi yog qhov dej dab dej ua dab tsi?
Scout piav qhia tias Maycomb nyob nees nkaum mais hauv av los ntawm Finch's Landing vim Sinkfield, tus tswv tsev noj mov uas muag cov mos txwv rau cov neeg Khab thiab cov neeg nyob, cov neeg soj ntsuam tsis txaus ntseeg los tsim Maycomb lub rooj zaum ntawm tsoomfwv ncig nws tavern .
