Rau starters, phosphorus yog ib tseem ceeb structural element nyob rau hauv DNA thiab RNA. Ob leeg ntawm cov noob caj noob ces muaj cov piam thaj-phosphate qaum. Phosphate plays lwm lub luag hauj lwm nyob rau hauv lub cell ib yam li ntawd nyob rau hauv DNA . Nws tshwm sim peb zaug hauv adenosine triphosphate, lossis ATP, uas yog ib qho tseem ceeb ntawm lub zog cia hauv hlwb.
Tsis tas li ntawd, vim li cas phosphate tseem ceeb hauv DNA?
Ib pawg phosphate tsuas yog ib qho phosphorus atom khi rau plaub oxygen atoms, tab sis nws muaj ntau lub luag haujlwm tseem ceeb. Nrog rau cov suab thaj thiab cov hauv paus, nws tsim cov nucleic acids, zoo li DNA thiab RNA. Raws li ib feem ntawm cov khoom siv hluav taws xob, xws li ATP, nws muab lub zog rau kev txav peb cov leeg.
Tsis tas li ntawd, puas muaj phosphorus hauv DNA? Phosphorus . Phosphorus yog qhov thib ob ntau tshaj ntxhia hauv tib neeg lub cev. Ntau li 85 feem pua ntawm phosphorus yog pom nrog calcium hauv cov pob txha thiab cov hniav. Phosphorus kuj yog ib feem ntawm DNA thiab RNA , cov txheej txheem caj ces ntawm txhua lub cell, uas ua rau nws tseem ceeb rau kev loj hlob ntawm tes thiab kev loj hlob.
Kuj Paub, vim li cas phosphorus tseem ceeb rau lub neej?
Phosphorus , 11th feem ntau lub hauv ntiaj teb, yog qhov tseem ceeb rau txhua yam muaj sia. Nws yog qhov tseem ceeb rau tsim DNA, cell membranes, thiab rau cov pob txha thiab cov hniav tsim nyob rau hauv tib neeg. Hnub no phosphorus yog ib qhov tseem ceeb feem ntawm kev lag luam chiv.
Muaj pes tsawg phosphorus nyob hauv lub qab ntuj khwb?

Kev kuaj cov zaub mov yog txheej txheem siv los xyuas tias cov khoom noj muaj kev nyab xeeb thiab tsis muaj cov kab mob phem, lossis nws tsuas muaj cov tshuaj ntxiv uas tau tso cai ntawm qib uas tau txais, lossis tias nws muaj cov qib zoo ntawm cov khoom xyaw tseem ceeb thiab nws cov ntawv tshaj tawm yog raug, los yog kom paub cov qib ntawm cov as-ham tam sim no
Vim li cas DNA thiaj li tseem ceeb hauv kev tshawb fawb forensic?
Forensics thiab DNA DNA tau tseem ceeb heev rau kev tshawb fawb forensic. Qhov kev tshawb pom ntawm DNA tau txhais tau hais tias qhov kev ua txhaum lossis kev ua txhaum ntawm tus neeg raug tshawb xyuas txog kev ua txhaum cai tuaj yeem txiav txim siab. Nws kuj txhais tau hais tias cov pov thawj tsis tshua muaj peev xwm tseem tuaj yeem muab cov ntsiab lus tseem ceeb hais txog tus neeg ua txhaum cai
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom

Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
