Kab mob yog tsis tsuas yog muaj ntau, ntau yam, thiab tseem ceeb rau ecology, lawv ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm lawv cov tswv. Ntxiv nrog rau kev xaiv lub siab uas lawv ua rau cov pej xeem ntawm tes, raws li tau hais los saum no, lawv txhawb kev hloov pauv ntawm cov noob thiab cov genomes thiab npaj cov noob hla cov kab.
Yog li ntawd, vim li cas peb thiaj kawm kab mob?
Kab mob yog cov kab mob sib kis me me uas xav tau tus tswv tsev nyob ntawm tes txhawm rau ua haujlwm thiab rov ua dua. Cov kws tshawb fawb kawm paub yuav ua li cas kab mob cuam tshuam nrog lwm cov kab mob, thiab lawv kawm cov qauv kom pom kev sib raug zoo ntawm cov qauv thiab kev ua haujlwm.
Ib yam nkaus, cov kab mob kis tau li cas? Cov qauv ntawm kab mob tso cai rau lawv ua tiav hauv lawv lub hom phiaj tseem ceeb- luam tawm . Lytic Cycle Ib zaug txuas rau tus tswv tsev cell, a kab mob vais lav txhaj nws cov nucleic acid rau hauv lub cell. Cov nucleic acid siv sijhawm ua haujlwm ib txwm muaj ntawm tus tswv tsev cell thiab tsim ntau daim ntawv theej ntawm virus ua protein txheej thiab nucleic acid.
Ib qho ntxiv, tus kab mob hauv biology yog dab tsi?
Kab mob vais lav . Ntau yam. Saib cov ntawv. A kab mob vais lav yog tus kab mob sib kis me me uas hloov pauv tsuas yog sab hauv cov kab mob muaj sia ntawm cov kab mob. Kab mob tuaj yeem kis tau txhua hom kev ua neej, los ntawm tsiaj thiab nroj tsuag mus rau cov kab mob me me, suav nrog cov kab mob thiab cov khoom qub.
Vim li cas cov kab mob tsis suav tias yog cov khoom muaj sia?
Kab mob , zoo li cov kab mob, yog tsom me me thiab ua rau tib neeg muaj kab mob. Kab mob kuj tsis muaj cov khoom ntawm yam muaj sia : Lawv muaj tsis muaj zog metabolism, lawv ua tsis loj hlob, lawv tsim tsis muaj pov tseg cov khoom, thiab lawv ua tsis teb rau stimuli. Lawv kuj tsis rov tsim dua ntawm nws tus kheej tab sis yuav tsum rov ua dua los ntawm kev ua phem nyob hlwb.

Vim li cas cov kws tshawb fawb ntxig cov noob rau tib neeg cov insulin rau hauv cov kab mob?
Recombinant DNA yog cov kws tshawb fawb thev naus laus zis tsim los uas ua rau nws muaj peev xwm ntxig tib neeg cov noob mus rau hauv cov khoom siv ntawm cov kab mob sib kis. Qhov "recombinant" micro-organism tam sim no tuaj yeem tsim cov protein nkag los ntawm tib neeg cov noob. Cov kws tshawb fawb tsim tib neeg cov insulin insulin hauv chav kuaj
Dab tsi yog kev tshawb fawb kws tshawb fawb txog keeb kwm keeb kwm los kwv yees lub sijhawm tuag piav qhia vim li cas kev kwv yees tsis tas yuav ncaj?
Ib tus kws tshawb fawb kws tshawb fawb txog keeb kwm tshawb fawb kev txhim kho kab ntawm kab hauv lub cev los kwv yees lub sijhawm tuag. Cov kev txiav txim siab no tsis yog qhov yooj yim ib txwm vim tias tus nqi ntawm cov kab menyuam loj hlob tau cuam tshuam los ntawm ib puag ncig cuam tshuam xws li thaj chaw nyob, huab cua, thiab huab cua puag ncig
Kev tshawb fawb txog kab mob kis tau zoo li cas?
Kev tshawb fawb txog kab mob kis tau zoo li cas? Kev tshawb fawb pib nrog cov lus nug tshawb fawb lossis cov lus xav kom teb. Piv txwv li, cov neeg uas haus cawv puas muaj feem yuav mob plawv ntau dua? Cov pej xeem txoj kev tshawb fawb tsim nyog tau raug xaiv thiab nthuav tawm qhov kev pheej hmoo kis mob yuav raug ntsuas
Thaum tus kws kho mob tau tso cai tso cai ntau npaum li cas yuav tsum muaj kev sib ntsib tim ntsej tim muag tshwm sim ntawm tus kws kho mob thiab cov kws kho mob qib siab uas tau sau npe rau tus nais maum?
Txawm li cas los xij, yog tias APRN lossis PA tau nyob hauv daim ntawv pom zoo tso cai nrog kws saib xyuas kws kho mob tsawg kawg tsib ntawm xya xyoo dhau los, cov rooj sib tham tim ntsej tim muag yuav tsum tshwm sim tsawg kawg ib hlis txog rau thawj hnub ntawm hnub uas tau pom zoo kos npe
Cov kab mob dab tsi ua rau cov kws kho mob tshawb fawb?
Molecular pathology feem ntau siv hauv kev kuaj mob qog noj ntshav thiab kab mob sib kis. Molecular Pathology feem ntau yog siv los tshuaj xyuas cov qog nqaij hlav xws li melanoma, brainstem glioma, qog hlwb thiab ntau lwm hom qog noj ntshav thiab kab mob sib kis
