Cov triangulation tooj yog txhais raws li lub xwmfab ntawm qhov nrug nruab nrab ntawm 2 qhov sib txuas 5-fold vertices. Cov triangulation tooj tuaj yeem txiav txim siab nrog cov duab hauv qab no tau npaj los ntawm Caspar thiab Klug (1963).

Khaws qhov no hauv kev xav, dab tsi yog capsid ntawm tus kab mob?

A capsid yog lub plhaub protein ntawm a kab mob vais lav . Nws suav nrog ntau cov txheej txheem oligomeric ua los ntawm cov protein hu ua protomers. Kev soj ntsuam 3-dimensional morphological subunits, uas yuav lossis tsis tuaj yeem sib cuam tshuam rau cov tib neeg cov protein, hu ua capsomeres. Cov capsid encloses cov khoom siv caj ces ntawm kab mob vais lav.

Tsis tas li ntawd, tus qauv ntawm tus kab mob yog dab tsi? Kab mob sib txawv hauv lawv qauv . A kab mob vais lav particle muaj DNA lossis RNA nyob rau hauv lub tsho tiv thaiv protein hu ua capsid. Cov duab ntawm capsid yuav txawv ntawm ib hom kab mob vais lav rau lwm tus. Lub capsid yog tsim los ntawm cov protein uas tau nkag los ntawm kis genes hauv lawv cov genome.

Tsis tas li nug, capsid yog dab tsi thiab nws ua haujlwm li cas?

Cov capsid yog lub plhaub protein uas ntim cov kab mob. Qhov no tsim lub chaw tiv thaiv me me nyob ib puag ncig cov khoom siv caj ces, tsim los tiv thaiv nws thiab kom ntseeg tau tias tus kab mob kis mus rau tus tswv tsev. Peb qhov yooj yim capsid cov duab yog icosahedral, helical, thiab prolate; txawm li cas los xij, cov duab ntawm capsids tuaj yeem sib txawv dav

Dab tsi yog cov protein tsis muaj capsid?

tsis yog - capsid cov protein pXI, Filamentous bacteriophage Txhais: Cov protein encoded los ntawm VIRAL GENOME uas tsim tawm hauv cov kab mob uas lawv kis tau, tab sis tsis ntim rau hauv VIRUS PARTICLES.
