Chitsanzo cha DNA double helix ichi chimalemera 22 * 22 * 68.5cm ndipo chimalemera makilogalamu 1. Chimagwiritsa ntchito mitundu yosiyanasiyana ya mankhwala a DNA, yokhala ndi bulaketi yokhazikika, yomwe imagwiritsidwa ntchito makamaka pophunzitsa zamoyo.

Kugawa mitundu kumasiyanitsa bwino maziko, shuga ndi phosphate; mawonekedwe ofanana a double helix amabereka mawonekedwe enieni a malo a molekyulu; zinthu zolimba zimakana kuwonongeka pafupipafupi; kukula kwakukulu koyima kumasintha kuti zigwirizane ndi kuwonera m'kalasi.

Aphunzitsi a sayansi ya zamoyo amaona mosavuta chidziwitso chosamveka bwino cha majini; ophunzira amamvetsetsa msanga kugwirizana kwa maziko ndi kapangidwe ka malo a DNA; masukulu amalandira zida zophunzitsira zoyeserera zolimba; malo asayansi amawonetsa sayansi yodziwika bwino.

Zabwino kwambiri kuposa zithunzi za m'mabuku olembedwa mwala wokhala ndi mawonekedwe ozungulira a miyeso itatu; zokhazikika bwino kuposa zitsanzo zosavuta zosonkhanitsidwa ndi manja zokhala ndi magawo okhazikika asayansi; kulemba zilembo zamitundu yambiri kumapangitsa kuti zigawo zizindikirike mwachangu kuposa zitsanzo za DNA zamitundu imodzi.

Chitsanzochi chikuwonetsa kapangidwe ka kapangidwe ka DNA double helix, momwe maunyolo awiri ofanana a polynucleocylic acid amapanga helix ya dzanja lamanja, yokhala ndi phosphoric acid pamwamba pa silinda, ma base pairwise pairwise pakati pa silinda, ndi base pairperson planes perpendicular to the silinda.

Zinthu Zofunika Chitsanzochi chapangidwa motsatira muyezo wa Unduna wa Maphunziro, ndipo chikugwirizana ndi muyezo wa J3212 woperekedwa ndi Unduna wa Maphunziro. Chitsanzochi ndi chitsanzo cha malangizo cha kapangidwe ka molekyulu ya DNA ya mtundu wa B kokulitsidwa nthawi 100 miliyoni (kogwiritsidwa ntchito kusukulu yapakati) ndi nthawi 200 miliyoni (kogwiritsidwa ntchito ku yunivesite). Chiphunzitso chodziwika bwino cha kapangidwe ka molekyulu ya DNA chinaperekedwa ndi Watson ndi Crick mu 1953, ndipo pambuyo pake chinatsimikiziridwa ndikusinthidwa ndi Wilkins. Chimafotokoza mokwanira makhalidwe ambiri a zamoyo ndi zakuthupi a mamolekyulu a DNA.

Maziko Aakulu Magawo Aakulu a chitsanzo ichi:1, helix iwiri ili ndi diameter ya 20A2, mtunda wa 34A, mtunda wa mawiri oyandikana nawo a maziko ndi 3.4A;3, kusiyana kwa njira ya maziko oyandikana ndi 36°;4, chiwerengero cha ma base pair pa spiral run ma pair 10;5, hydrogen bond length 25-40A

6, kukula kwa m'lifupi mwa ngalande ndi pafupifupi 20A, 14A.

Yapitayi: Kukula kwa Moyo wa Munthu Chitsanzo cha Kapangidwe ka Mapazi a Munthu ndi Minofu ya Plantar Mitsempha ya Mitsempha ya Mitsempha Mafupa Olumikizana Mitsempha Yophunzitsira ndi Kuphunzira Zachipatala

Ena: Chophunzitsira Chopaka Mabala a Dzanja Chodulidwa ndi Chida Choyesera Kutulutsa Magazi cha Maphunziro a TCCC
