Gene - ndi chiyani ichi? Amazing zodabwitsa sayansi chibadwa

Chifukwa mwamuna ayang'ana kuti njira ndi wina? N'chifukwa chiyani ana amafanana ndi makolo awo, agogo, abale ndi alongo? Funso limeneli anthu chidwi kale zikamera wa sayansi ya chibadwa. Iye anaonekera ndi posachedwapa. The anayambitsa sayansi amati Gregor Mendel, amene anakhalapo zaka za m'ma XIX ndi kukonza malamulo angapo, chimene pali cholowa cha makhalidwe ena.

Kumayambiriro kwa zaka za m'ma XX, malowa Asayansi chidwi ndi walandira chitukuko kwambiri. Mu 1909 wakhala anakonza ndi kugwiritsa ntchito mfundo jini lapansi. Gene - ali mbali ya unyolo DNA, zonse bwino awiri helix, lomwe likupezeka mu yonse yochepetsetsa anthu ndipo amanyamula mfundo zonse za izo. DNA ndi anapezeka ku maselo nyongolosi, ndipo pamene pophatikizana ndi osakaniza a DNA majeremusi awiri kubala dera atsopano ndi wapadera kuti Chili DNA ndi kholo zamoyo osati kokha, komanso mbali zina za maunyolo a makolo awo. Gene - gulu la zokhudza mbali iliyonse kapena gulu la mbali ya chamoyo. Ena majini pang'ono alipo mfundo ndiyotengera mwa iwo, moti aliyense cholengedwa anaonekera kudzera kubereka, ndi wapadera kwambiri. Akukhulupirira kuti zonse zokhudza chamoyo ndi ndiyotengera ndi chibadwa osachepera 30-50 zikwi, koma iwo angakhale zambiri. Ndiko, lililonse nkhope, tsitsi, khungu, maso, mawonekedwe msomali njira zonse kagayidwe kachakudya - zizindikiro zonse izi gulu kapena jini payekha. Ndi kotero kufufuza ndi kumvetsa! Izi ndi zimene asayansi ndi chinkhoswe.

Maselo chibadwa - mmodzi wa zigawo zina za sayansi ambiri - anachita kuphunzira dongosolo la jini lapansi. Malinga ndi kafukufuku, matabwa ake osalunjika conventionally imakhala mbali ziwiri: 'kala' ikusonyeza ndipo sanali 'kala' ikusonyeza, amene akutchedwa, motero, ndipo exon nitrone. kupezeka anapangidwa pambuyo kuphunzira DNA ya eukaryotes, kuti ndi matupi a chamoyo amene maselo muli phata. Kwenikweni, ndi DNA kumaphatikizapo nucleotides, amene encode nkhani zonse pa thupi. Ndipo kuchokera amazionera zimapangidwira onse mapuloteni izi.

Latest atulukira ndiponso achita wa chibadwa linapereka mankhwala, kuswana, zamoyo, forensics ndi maphunziro ena a sayansi. zolondola pa kudziwa ali jini makamaka - ndicho chinsinsi zochizira matenda ambiri. Mukhoza kupeza chiyambi cha ichi kapena kuti munthu kutsimikiza kapena kukana ubale wa anthu osiyana, ndi zina zambiri. M'tsogolo, asayansi adzatha yesezera ndi kukonza jini akhoza kuwina matenda ambiri, kubweretsa latsopano mbewu zosiyanasiyana ndipo Mitundu nyama. Si ofuna?

Chibadwa, pali chidwi lingaliro - jini otaya. Kumatanthauza maonekedwe a anthu limodzi la ambiri majini chibadidwe ena
anthu chifukwa utuluke kusamuka. Ndiko kuti, ngati tigwiritsa ntchito mawu amenewa kwa anthu, chisakanizo cha mafuko awiri, kuloŵerera.

Chibadwa - zodabwitsa ndi chidwi kwambiri sayansi, amene m'tsogolo akhoza kukhala mbali imodzi yofunika kwambiri ndipo zingamuthandize. Iwo osati Mzimuyo ati adzakhale, koma tingathe kupeza chimene icho chinali. Mothandizidwa ndi mzimuwo, mungathe kutsimikizira kapena kutsutsa ziphunzitso alipo ya maonekedwe a munthu.
