Cov central dogma yog lub moj khaum los piav qhia txog qhov ntws ntawm cov ntaub ntawv caj ces los ntawm DNA rau RNA rau protein ntau . Thaum cov amino acids koom ua ke los ua ib qho protein ntau molecule, npe protein synthesis . Txhua protein ntau muaj nws tus kheej cov lus qhia, uas yog encoded nyob rau hauv seem ntawm DNA, hu ua noob.
Kuj paub yog, dab tsi yog lub hauv paus dogma?
Cov central dogma ntawm molecular biology piav txog cov txheej txheem ob-kauj ruam, kev hloov pauv thiab kev txhais lus, uas cov ntaub ntawv hauv cov noob ntws mus rau hauv cov protein: DNA → RNA → protein. Kev hloov pauv yog kev sib txuas ntawm RNA daim qauv ntawm ib ntu ntawm DNA. RNA yog tsim los ntawm enzyme RNA polymerase.
Ib tug kuj yuav nug, vim li cas lub hauv paus dogma tseem ceeb? Hauv kev xaus, lub qhov tseem ceeb ntawm central dogma rau niaj hnub biology yog tias tsis muaj cov txheej txheem no rov ua dua ntawm hom yuav tsis tshwm sim raws li cov ntaub ntawv caj ces yuav tsis tuaj yeem khaws cia thiab tsim cov proteins uas tseem ceeb hauv cov txheej txheem biochemical.
Cov lus nug tseem yog, dab tsi yog 3 ntu ntawm lub hauv paus dogma?
Replication, Transcription, thiab Translation yog peb lub ntsiab cov txheej txheem siv los ntawm txhua lub hlwb los tuav lawv cov ntaub ntawv caj ces thiab hloov cov ntaub ntawv caj ces hauv DNA rau hauv cov khoom lag luam, uas yog RNAs lossis cov protein, nyob ntawm cov noob.
Central dogma txhais li cas?
Cov Central Dogma ntawm Molecular Biology hais tias DNA ua RNA ua cov proteins (Daim duab 1). Daim duab 1 | Cov Central Dogma ntawm Molecular Biology: DNA ua RNA ua cov proteins. Cov txheej txheem uas DNA tau theej rau RNA yog hu ua transcription, thiab qhov uas RNA siv los tsim cov proteins hu ua txhais lus.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi yog 3 qhov chaw ntawm lub hauv paus dogma?
Replication, Transcription, thiab Kev Txhais Lus yog peb txoj haujlwm tseem ceeb siv los ntawm txhua lub hlwb los tswj lawv cov ntaub ntawv caj ces thiab hloov cov ntaub ntawv caj ces encodedin DNA rau hauv cov khoom lag luam, uas yog RNAs lossis cov proteins, nyob ntawm cov noob
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
