Retrotransposons yog cov noob caj noob ces uas kis ntawm qhov rov qab ntawm RNA intermediates. Lawv yog cov muaj ntau ntawm cov kab mob fungal feem ntau thiab tuaj yeem ua rau muaj ntau yam ntawm cov caj ces thiab cov genomic rearrangements.
cov transposons tuaj qhov twg?
Transposons tau pom thawj zaug hauv pob kws (pob txha) thaum xyoo 1940 thiab '50s los ntawm Asmeskas kws tshawb fawb Barbara McClintock, nws txoj haujlwm yeej nws qhov khoom plig Nobel rau Physiology lossis Tshuaj hauv xyoo 1983. Txij li thaum McClintock qhov kev tshawb pom, peb hom kev hloov pauv tau raug txheeb xyuas.
Puas retrotransposons los ntawm cov kab mob?
Txawm hais tias nws muaj peev xwm ua tau tias tag nrho cov retrotransposons yog derivatives ntawm kis kab mob, nws zoo li intuitive hais tias nyob rau hauv lub ntiaj teb no scale ib yam dab tsi nyuaj (ib tug kab mob) keeb kwm evolved los ntawm tej yam yooj yim (ib retrotransposon).
Retroelements pom nyob qhov twg?
Cov retroelements muaj ntau qhov sib dhos ntawm cov khoom sib txuas ntawm cov molecular raws li tuaj yeem pom nyob qhov twg. Nrog rau kev zam ntawm cov kab mob retroviruses lawv tus kheej, retroelements yog cov kab mob kab mob uas nyob hauv cov genomes ntawm tag nrho cov eukaryotes thiab ntau prokaryotes.
Qhov txawv ntawm retrovirus thiab retrotransposon yog dab tsi?
Ib qhov sib txawv tseem ceeb ntawm retroviruses thiab LTR retrotransposons yog txawm tias lawv kis tau Retroviruses muaj peev xwm txav ntawm cov hlwb, qhov LTR retrotransposons tsuas tuaj yeem tso cov ntawv theej tshiab rau hauv genome tam sim no. nyob rau hauv tib lub cell, thiab cia siab rau feem ntau ntawm ntsug kis mus rau ntau tiam.
