Ma Chromosomu: Kapangidwe Kofunikira mu Ma Genetic Ma Chromosomu ndi kapangidwe kolimba komwe kamapezeka mu nucleus ya maselo a eukaryotic ndipo kamayang'anira kunyamula chidziwitso cha majini mu mawonekedwe a DNA. Chamoyo chilichonse chokhala ndi nucleus (eukaryotic) chili ndi ma chromosome, kuphatikiza anthu, nyama, zomera, ndi bowa. M'nkhaniyi, tifufuza mbali zosiyanasiyana za ma chromosome, kuphatikiza kapangidwe kawo, ntchito yawo, ndi kufunika kwawo… Werengani zambiri

Chochitika ichi n'chofunikira kwambiri pa moyo watsiku ndi tsiku, kuyambira kulankhulana kwa anthu ndikusangalala ndi nyimbo mpaka kugwiritsa ntchito ukadaulo monga sonar ndi ultrasound. Munkhaniyi, tifufuza malingaliro osiyanasiyana okhudzana ndi magwero a mawu kudzera… Werengani zambiri
Kukonza DNA kapena Kuyika Ma CD Mkati mwa Maselo Pa mulingo wa mamolekyulu, moyo padziko lapansi umamangidwa pamaziko a chidziwitso cha majini chomwe chili mu mamolekyulu a DNA. DNA, kapena deoxyribonucleic acid, ndi polima yomwe imasunga malangizo a zamoyo ofunikira pakukula, kugwira ntchito, kukula, ndi kuberekana kwa zamoyo zonse. Ngakhale kuti DNA ili ndi mitundu inayi yokha ya ma nucleotide—adenine (A), thymine (B), ndi ma nucleotide (C)... Werengani zambiri
Chitsanzo Vuto: Liwiro la Phokoso Liwiro la phokoso ndi lingaliro lofunika kwambiri mu fizikisi lomwe limafotokoza momwe phokoso, kapena mafunde a phokoso, amayendera kudzera mu sing'anga. Sing'anga iyi ikhoza kukhala mpweya, madzi, kapena ngakhale chinthu cholimba. Lingaliro ili ndi lofunika kwambiri pa ntchito zosiyanasiyana, kuyambira ukadaulo wa sonar mpaka ma acoustics a m'chipinda. Kuti timvetse liwiro la phokoso, tiyenera… Werengani zambiri
Kubwerezabwereza kwa DNA Kubwerezabwereza kwa DNA ndi njira yofunikira yachilengedwe yomwe imalola maselo kubwerezabwereza zinthu zawo za majini asanayambe kugawikana kwa maselo, kotero kuti selo lililonse la mwana wamkazi limalandira kopi yofanana ya DNA. Njirayi ndiyo maziko a cholowa cha majini ndipo imagwira ntchito yofunika kwambiri pakukula, kukonza, ndi kusamalira zamoyo. Kumvetsetsa momwe DNA imachitira sikuti ndikofunikira kokha mu biology… Werengani zambiri

Popanda mafunde a phokoso, sitikanatha kumva kapena kulankhulana mosavuta. Nkhaniyi ifotokoza za lingaliro loyambira la mafunde a phokoso ndikupereka zitsanzo za mavuto kuti mumvetse bwino nkhaniyi. Lingaliro Loyambira la Mafunde a Phokoso Mafunde a phokoso… Werengani zambiri
Chitsanzo cha Watson ndi Crick cha DNA Molecular Kumayambiriro kwa zaka za m'ma 20, kumvetsetsa kwathu majini kunali kochepa kwambiri. Ngakhale kuti zinali zomveka kuti majini anali mayunitsi oyambira a cholowa, kapangidwe kawo katsatanetsatane ndi momwe amagwirira ntchito sizinali chinsinsi. Kupambana kwakukulu kunabwera mu 1953 pamene asayansi awiri achichepere, James Watson ndi Francis Crick, adapereka chitsanzo cha kapangidwe ka DNA komwe kanakhala maziko a… Werengani zambiri
