Cov kws tshawb fawb ntawm JCVI tau tsim thawj lub xov tooj nrog cov khoom siv hluavtaws genome hauv xyoo 2010. hauv lab. Qhov no yog thawj kab mob nyob rau hauv keeb kwm ntawm lub neej nyob rau hauv lub ntiaj teb no muaj ib tug tag nrho synthetic genome.

Lub neej puas tsim tau?

Lub Tsib Hlis 2019, cov kws tshawb fawb tau tshaj tawm qhov tseem ceeb tshiab hauv kev tsim cov khoom hluavtaws tshiab (tejzaum nws tuaj yeem tsim tau) daim ntawv ntawm lub neej siv tau, qhov sib txawv ntawm cov kab mob Escherichia coli, los ntawm kev txo qis ntawm 64 codons hauv cov kab mob genome. rau 59 codons xwb, thiaj li yuav encode 20 amino acids.

Thaum twg cov kws tshawb fawb tsim lub neej hluavtaws?

In 2010, Asmeskas cov kws tshawb fawb tau tshaj tawm kev tsim lub ntiaj teb thawj cov kab mob nrog cov genome hluavtaws. Cov kab mob, Mycoplasma mycoides, muaj ib qho genome me dua E coli - txog 1m puag khub - thiab tsis tau tsim dua tshiab.

Puas muaj tus kws tshawb fawb tsim lub neej?

Cov kws tshawb fawb tau tsim cov kab mob uas muaj sia nyob uas nws DNA yog tib neeg tsim - tej zaum yog hom tshiab ntawm lub neej, cov kws tshaj lij tau hais, thiab lub ntsiab lus tseem ceeb hauv thaj chaw ntawm cov khoom siv hluavtaws. … "Nws yog ib qho tseem ceeb," Tom Ellis, tus thawj coj ntawm Lub Chaw rau Synthetic Biology ntawm Imperial College London, uas tsis koom nrog txoj kev kawm tshiab.

Ntawm twg yog thawj zaug nyob hauv ntiaj teb?

Qee cov kws tshawb fawb kwv yees tias 'lub neej' pib ntawm peb lub ntiaj teb thaum ntxov li plaub txhiab xyoo dhau los. Thiab thawj yam uas muaj sia nyob yog yooj yim, ib leeg-hlwb, cov kab mob hu ua prokaryotes(lawv tsis muaj cell membrane thiab cell nucleus).
