Muenzaniso weDNA Yekuyedza Kwekurapa/Modhero Yehupenyu Biology Yekudzidzisa Kwekurapa Double Helix DNA Structure Model
Iyi modhi yeDNA double helix ine huremu hwe22 * 22 * 68.5cm ine huremu hwe1kg. Inoshandisa musanganiswa wemavara akasiyana-siyana wechikamu chimwe nechimwe cheDNA, ine bracket yakasimba, inoshandiswa zvakanyanya pakudzidzisa biology experiment.
Kuronga mavara kunonyatsosiyanisa mabhesi, shuga nephosphate; chimiro che double helix chakajairika chinounza chimiro chechokwadi chenzvimbo yemamorekuru; zvinhu zvakasimba zvinoramba kukuvara kunowanzoitika; saizi hombe yakamira inoenderana nekutarisa kwekirasi pamwe chete.
Vadzidzisi vebhayoloji vanonyatsoona ruzivo rwemajini rwusinganyatsooneki; vadzidzi vanokurumidza kunzwisisa kubatana kwebase uye chimiro cheDNA; zvikoro zvinowana zvekushandisa zvekuedza zvakasimba; nzvimbo dzesainzi dzinoona kuratidzwa kwesainzi kwakakurumbira.
Mifananidzo yemabhuku ekuverenga yakanakisa kupfuura yemhando dzakasiyana-siyana ine mativi matatu ekutenderera; yakajairika kupfuura mienzaniso yakaunganidzwa nemaoko ine huwandu hwakatarwa hwesainzi; kumaka mavara akawanda kunoita kuti kuzivikanwa kwezvikamu kukurumidze kupfuura mienzaniso yeDNA ine ruvara rumwe chete.

Modhi iyi inoratidza chimiro cheDNA double helix, umo macheni maviri akafanana epolynucleocylic acid anoumba right-handed helix, ine phosphoric acid pamusoro pecylinder, base pairwise pairs pakati pecylinder, uye base pair planes dzakatarisana necylinder.
Zvinhu Zviri Mukati Modhi iyi yakagadzirwa zvichienderana neMinistry of Education standard, uye inoenderana neJ3212 standard yakapihwa neMinistry of Education. Modhi iyi imodhi yekudzidzisa yeB-type DNA molecular structure yakakura ka100 miriyoni (yekushandisa kuchikoro chepakati) uye ka200 miriyoni (yekushandisa kuyunivhesiti). Dzidziso yakakurumbira yedouble helix structure yeDNA molecule yakakurudzirwa naWatson naCrick muna 1953, uye yakazosimbiswa uye yakagadziridzwa naWilkins. Inotsanangura zvinogutsa hunhu hwakawanda hwebiological uye physical hwemaDNA molecules.
Hwaro Huru Zviyero zvikuru zvemuenzaniso uyu:1, denderedzwa repiri rine dhayamita ye20A2, pitch 34A, nzvimbo yepakati pemapeya epasi ari pedyo 3.4A;3, musiyano wenzira yenheyo dziri pedyo ndeye 36°;4, huwandu hwemapeya ehwaro pakufamba kwemupendero wedenderedzwa hune mapeya gumi;5, kureba kwehydrogen bond 25-40A
6, saizi yehupamhi hwegomba iri inenge 20A, 14A.
