Qhov sib txawv tseem ceeb ntawm muton thiab recon yog tias muton yog chav tsev me me ntawm DNA muaj peev xwm ntawm kev hloov pauv tuaj yeem tshwm sim thaum recon yog qhov tsawg tshaj plaws ntawm DNA uas tuaj yeem rov ua dua.
Gene yog lub hauv paus ntawm kev sib hloov. Nws muaj cov ntaub ntawv tshwj xeeb ntawm caj ces los tsim cov protein tshwj xeeb. Qhov tseeb, nws yog ib qho nucleotide ib ntus uas cov noob caj noob ces zais. Gene muaj ob peb chav me me. Nws muaj ib tug functional unit, recombination unit thiab ib tug mutation unit. Yog li, recon yog lub recombination unit ntawm ib tug noob, thaum muton yog chav tsev ntawm kev hloov. Muton nyob rau hauv lub recon, thiab ib tug recon muaj ob peb mutons.
Muton yog dab tsi?
Muton yog thaj chaw intragenic. Nws yog chav tsev ntawm kev hloov pauv hauv cov noob. Qhov tseeb, nws yog ib chav me me. Nws tuaj yeem yog ib lub hauv paus lossis ob peb lub hauv paus txij li qhov kev hloov pauv tuaj yeem tshwm sim vim yog ib lub hauv paus hloov lossis ntau lub hauv paus. Yog li ntawd, ib qho nucleotide yog qhov tsawg tshaj plaws muton. Thaum xav txog qhov ntau thiab tsawg ntawm cistron, recon thiab muton, muton yog qhov tsawg tshaj plaws.
Daim duab 01: Kev hloov pauv
Ib tus recon tuaj yeem muaj ob peb mutons. Ib yam li ntawd, ib lub cistron tuaj yeem muaj ob peb recons. Mutons yog lub luag haujlwm rau kev tsim cov kab mob mutant tshiab vim muton yog qhov chaw ntawm cov noob uas qhov kev hloov pauv tshwm sim.
Recon yog dab tsi?
Recon yog hais txog chav hloov pauv hauv cov noob. Nws yog chav tsev me tshaj plaws uas muaj peev xwm ua kom rov qab ua dua. Recon loj dua ib tug muton, thiab nws muaj peev xwm muaj ob peb mutons thiab ib tug muton.
Daim duab 02: Recombination
Recon tuaj yeem lees paub los ntawm kev hloov pauv uas ua rau cov amino acid sib lawv liag. Ntxiv mus, nws kuj tuaj yeem txheeb xyuas los ntawm nucleotide ib ntus ntawm cistron.
Dab tsi yog qhov zoo sib xws ntawm Muton thiab Recon?
- Ob leeg yog qhov tsawg tshaj plaws hauv cov noob.
- American geneticist S Benzer qhia cov ntsiab lus no.
Qhov txawv ntawm Muton thiab Recon yog dab tsi?
Muton yog qhov tsawg tshaj plaws ntawm cov noob uas tuaj yeem hloov pauv. Ntawm qhov tod tes, recon yog ntu ntawm DNA lossis chav tsev ntawm DNA uas tuaj yeem rov ua dua. Yog li, qhov no yog qhov txawv ntawm muton thiab recon.
Ntxiv mus, qhov sib txawv ntxiv ntawm muton thiab recon yog tias ib tus recon tuaj yeem muaj ob peb mutons thaum muton yog ib chav me dua li recon. Qhov no kuj yog qhov sib txawv ntawm muton thiab recon. Tsis tas li ntawd, chav tsev me me ntawm muton yog nucleotide. Nyob rau hauv sib piv, qhov tsawg tshaj plaws chav tsev ntawm lub recon yog ib feem me me ntawm DNA uas yuav undergo recombination.
Summary – Muton vs Recon
Muton yog chav me me ntawm chromosome uas tau hloov pauv hloov pauv. Nyob rau hauv sib piv, recon yog qhov tsawg tshaj plaws chav tsev muaj peev xwm mus undergoing recombination. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm muton thiab recon. Ob leeg yog units ntawm ib tug gene. Txij li thaum kev hloov pauv tuaj yeem tshwm sim hauv ib puag ncig lossis nucleotide, muton yog qhov tsawg tshaj plaws piv rau recon. Yog li, recon tuaj yeem muaj ob peb mutons.
