Thiab koj paub dab tsi noob?

Cov nqe lus nug ntawm yog dab tsi cov noob yog heev nthuav. Nyob rau hauv ib tes, txhua leej txhua tus paub hais tias cov kev tshuaj ntsuam genetic ntaub ntawv yog kis tau ntawm leej niam leej txiv rau tus me nyuam, tab sis nws tus kheej cia mechanism cov ntaub ntawv no yog paub tsis meej rau cov neeg feem coob. Caj sijhawm muaj tag nrho cov sentient beings, thiab lawv txiav txim tag nrho cov thawj cov ntaub ntawv nyob rau hauv lub cev: nws cov tsos, teej tug mus rau ib tug zoo, yam ntxwv nta, thiab ntau dua.

Muaj coob tus neeg nco ntsoov los ntawm lub tsev kawm ntawv hoob biology kawm, cov ntaub ntawv no yog muab cia rau hauv DNA - ib qho ntawm qhov yooj yim nucleic acid. Hais tias cov saw ntawm deoxyribonucleic acid thiab txiav txim seb tus neeg ntawm ib tug tsiaj los yog tib neeg nyob rau hauv cov nqe lus ntawm tej hlab ntshav. Tab sis yuav ua li cas mus hais txog mus "DNA" thiab lub tswvyim ntawm "noob"? Cia peb kawm saib nyob rau hauv cov ntsiab lus uas.

Yuav ua li cas yog cov noob thiab DNA?

Nyob rau hauv cov qauv ntawm cov deoxyribonucleic acid tseem ceeb rau tej cheeb tsam uas yog lub luag hauj lwm rau lub hav zoov ntawm tej yam lus qhia los ntawm nws tus tswv. Nws yog ib cov chaw hauv lub saw yog cov noob. Lawv muaj ntaub ntawv qhia txog cov protein ntau thiab protein - yog ib tug organic tsev ntaub. Tag nrho cov Cheebtsam ntawm deoxyribonucleic acid muaj nyob rau hauv txhua ntawm tes ntawm lub cev, ua genome ntawm ib tug nyob qab. Ib feem ntawm cov ntaub ntawv no yog kis tau los ntawm cov txiv, cov lwm yam - yog pub los ntawm leej niam.

Muaj peev xwm decipher lub caj ntaub ntawv niaj hnub no muaj peev xwm yuav heev meej teev cov kev sib raug zoo, xws li leej txiv. Nyob rau hauv qhov tseeb, cov lus nug ntawm yog dab tsi cov noob yog complex txaus los teb nws nyob rau hauv ib tug nutshell. Tab sis metaphors lus yuav piv cov ntaub ntawv. Peb sawv cev ntawm ib cov saw ntawm DNA nyob rau hauv daim ntawv ntawm ib phau ntawv txog ib qho kev nyob siab, ces lub noob yuav tsum tau ib tug neeg cov lus ntawm cov nplooj ntawv hauv phau ntawv no. Txhua yam ntawm cov lus muaj xwb 4 cov tsiaj ntawv, tab sis lawv muaj peev xwm ntxiv mus unlimited tooj ntawm cov nqe lus. Hais tias yog, cov noob yog ib qho alternation ntawm plaub tshuaj tebchaw. Cov no yog hu ua nucleobases adenine, cytosine, guanine thiab thymine. Ib me ntsis metamorphosis nyob rau hauv lub caj code, nrog qhov kev hloov los ntawm ib tug tshuaj compound mus rau lwm lub, ua rau ib tug kev hloov nyob rau hauv "cov lus" txiav txim zoo li ib tug tag nrho. Thiab raws li peb paub, txhua noob yog lub luag hauj lwm rau cov qauv ntawm cov protein. Lwm yam ntaub ntawv nyob rau hauv nws - ib tug txawv protein qauv - cov yam ntxwv tshiab ntawm tus kab mob. Tab sis xws li alternations yog tau yog hais tias qhov hloov lwm lub tsev ntawm caj ces, ces tus kwv tij thiab cov muam ntawm lub tib lub niam txiv yog txawv los ntawm txhua lwm yam, txawm yog hais tias lawv yog tib yam cov menyuam ntxaib. Tab sis cov ntaub ntawv nyob hauv peb lub genome, tseem unchanged txij thaum yug mus tuag.

laus noob

Lub neej expectancy thiab lub mechanism ntawm muaj hnub nyoog txog cov kev hloov uas tshwm sim rau ib tug neeg sab nraud ntawm lub caj ntaub ntawv. daim kev cai, uas yuav tau lub luag hauj lwm rau kev laus, yog nrhiav tsis tau, tab sis cov soj ntsuam ntawm hais tias nws yog tsis zoo li hais tias xws li cov ntaub ntawv uas yog cia nyob rau hauv lub DNA nyob rau hauv ib qhov chaw. Laus - ib tug complex txheej txheem uas muaj feem xyuam rau tag nrho cov lub cev, qhov uas peb "luminaries ntawm science" tseem muaj ib tug ntev kev tshawb fawb nyob rau hauv no cov kev taw qhia.

Nthuav, tab sis heev provocative taw tes ntawm view ntawm caj tau nyob rau hauv ib phau ntawv luam tawm nyob rau hauv 1976. Nws sau lus Askiv ethologist K.R.Dokinz. "Lub qia dub Noob" - ib tug scientific ua hauj lwm nyob rau hauv uas theorizes uas lub tsav tsheb quab yuam ntawm evolution yog muaj lub siab xav ua rau kom cov adaptability ntawm lub hom. Xaiv yuav siv sij hawm qhov chaw nyob rau hauv lub caj theem, thiab tsis nyob rau theem ntawm coob thiab tej neeg. Feem ntau, ib tug exhaustive lus teb rau lo lus nug: "Yuav ua li cas yog lub noob", thaum kom meej meej tsis tau. Feem ntau cov yuav, lub tswv yim ntawm cov khej ntawm DNA nrog txoj kev loj hlob ntawm science yuav tsum muab kho tshiab cov ntaub ntawv thiab tiag hloov.
